misc/ruby-pry: update to 0.12.2

pkgsr change:
* Remove @PREFIX@ from ALTERNATIVES file.

### [v0.12.2][v0.12.2] (November 12, 2018)

#### Bug fixes

* Restore removed deprecations, which were removed by accident due to a bad
  rebase.

### [v0.12.1][v0.12.1] (November 12, 2018)

#### Bug fixes

* Stopped creating a new hash each time `Pry::Prompt#[]` is invoked
  ([#1855](https://github.com/pry/pry/pull/1855))
* Fixed `less` pager not working when it's available
  ([#1861](https://github.com/pry/pry/pull/1861))

### [v0.12.0][v0.12.0] (November 5, 2018)

#### Major changes

* Dropped support for Rubinius ([#1785](https://github.com/pry/pry/pull/1785))

#### Features

* Added a new command, `clear-screen`, that clears the content of the screen Pry
  is running in regardless of platform (Windows or UNIX-like)
  ([#1723](https://github.com/pry/pry/pull/1723))
* Added a new command, `gem-stat`, that prints gem statistics such as gem
  dependencies and downloads ([#1707](https://github.com/pry/pry/pull/1707))
* Added support for nested exceptions for the `wtf` command
  ([#1791](https://github.com/pry/pry/pull/1791))
* Added support for dynamic prompt names
  ([#1833](https://github.com/pry/pry/pull/1833))

  ```rb
  # pryrc
  Pry.config.prompt_name = Pry.lazy { rand(100) }

  # Session
  [1] 80(main)>
  [2] 87(main)>
  [3] 30(main)>
  ```
* Added support for XDG Base Directory Specification
  ([#1609](https://github.com/pry/pry/pull/1609),
  [#1844](https://github.com/pry/pry/pull/1844),
  ([#1848](https://github.com/pry/pry/pull/1848)))
* Removed the `simple-prompt`. Use `change-prompt simple` instead. The
  `list-prompt` command was removed and embedded as `change-prompt --list`
  ([#1849](https://github.com/pry/pry/pull/1849))

#### API changes

* The following methods started accepting the new optional `config` parameter
  ([#1809](https://github.com/pry/pry/pull/1809)):
  * `Pry::Helpers.tablify(things, line_length, config = Pry.config)`
  * `Pry::Helpers.tablify_or_one_line(heading, things, config = Pry.config)`
  * `Pry::Helpers.tablify_to_screen_width(things, options, config = Pry.config)`
  * `Pry::Helpers::Table.new(items, args, config = Pry.config)`

  You are expected to pass a session-local `_pry_.config` instead of the global
  one.

* Added new method `Pry::Config.assign`, for creating a Config non-recursively
  ([#1725](https://github.com/pry/pry/issues/1725))
* Added `Pry.lazy`, which is a helper method for values that need to be
  calculated dynamically. Currently, only `config.prompt_name` supports it
  ([#1833](https://github.com/pry/pry/pull/1833))
* `Pry::Prompt` responds to `.[]`, `.all` & `.add` now. The `Pry::Prompt.add`
  method must be used for implementing custom prompts. See the API in the
  documentation for the class ([#1846](https://github.com/pry/pry/pull/1846))

#### Breaking changes

* Deleted the `Pry::Helpers::Text.bright_default` alias for
  `Pry::Helpers::Text.bold` ([#1795](https://github.com/pry/pry/pull/1795))
* `Pry::Helpers.tablify_to_screen_width(things, options, config = Pry.config)`
  requires `options` or `nil` in place of them.
* `Pry::Helpers::Table.new(items, args, config = Pry.config)` requires `args`
  or `nil` in place of them.
* Completely revamped `Pry::HistoryArray`
  ([#1818](https://github.com/pry/pry/pull/1818)).
  * It's been renamed to `Pry::Ring`
    ([#1817](https://github.com/pry/pry/pull/1817))
  * The implementation has changed and as result, the following methods were
    removed:
    * `Pry::Ring#length` (use `Pry::Ring#count` instead)
    * `#empty?`, `#each`, `#inspect`, `#pop!`, `#to_h`
  * To access old Enumerable methods convert the ring to Array with `#to_a`
  * Fixed indexing for elements (e.g. `_pry_.input_ring[0]` always return some
    element and not `nil`)
* Renamed `Pry.config.prompt_safe_objects` to `Pry.config.prompt_safe_contexts`
* Removed deprecated `Pry::CommandSet#before_command` &
  `Pry::CommandSet#after_command` ([#1838](https://github.com/pry/pry/pull/1838))

#### Deprecations

* Deprecated `_pry_.input_array` & `_pry_.output_array` in favour of
  `_pry_.input_ring` & `_pry_.output_ring` respectively
  ([#1814](https://github.com/pry/pry/pull/1814))
* Deprecated `Pry::Command#text`. Please use `#black`, `#white`, etc. directly
  instead (as you would with helper functions from `BaseHelpers` and
  `CommandHelpers`) ([#1701](https://github.com/pry/pry/pull/1701))
* Deprecated `_pry_.input_array` & `_pry_.output_array` in favour of
  `_pry_.input_ring` and `_pry_.output_ring` respectively
  ([#1817](https://github.com/pry/pry/pull/1817))
* Deprecated `Pry::Platform`. Use `Pry::Helpers::Platform` instead. Note that
  `Pry::Helpers::BaseHelpers` still includes the `Platform` methods but emits a
  warning. You must switch to `Pry::Helpers::Platform` in your code
  ([#1838](https://github.com/pry/pry/pull/1838),
  ([#1845](https://github.com/pry/pry/pull/1845)))
* Deprecated `Pry::Prompt::MAP`. You should use `Pry::Prompt.all` instead to
  access the same map ([#1846](https://github.com/pry/pry/pull/1846))

#### Bug fixes

* Fixed a bug where `cd Hash.new` reported `self` as an instance of Pry::Config
  in the prompt ([#1725](https://github.com/pry/pry/pull/1725))
* Silenced the `Could not find files for the given pattern(s)` error message
  coming from `where` on Windows, when `less` or another pager is not installed
  ([#1767](https://github.com/pry/pry/pull/1767))
* Fixed possible double loading of Pry plugins' `cli.rb` on Ruby (>= 2.4) due to
  [the `realpath` changes while invoking
  `require`](https://bugs.ruby-lang.org/issues/10222)
  ([#1762](https://github.com/pry/pry/pull/1762),
  [#1774](https://github.com/pry/pry/pull/1762))
* Fixed `NoMethodError` on code objects that have a comment but no source when
  invoking `show-source` ([#1779](https://github.com/pry/pry/pull/1779))
* Fixed `negative argument (ArgumentError)` upon pasting code with tabs, which
  used to confuse automatic indentation
  ([#1771](https://github.com/pry/pry/pull/1771))
* Fixed Pry not being able to load history on Ruby 2.4.4+ when it contains the
  null character ([#1789](https://github.com/pry/pry/pull/1789))
* Fixed Pry raising errors on `cd`'ing into some objects that redefine
  `method_missing` and `respond_to?`
  ([#1811](https://github.com/pry/pry/pull/1811))
* Fixed bug when indentation leaves parts of input after pressing enter when
  Readline is enabled with mode indicators for vi mode
  ([#1813](https://github.com/pry/pry/pull/1813),
  [#1820](https://github.com/pry/pry/pull/1820),
  [#1825](https://github.com/pry/pry/pull/1825))
* Fixed `edit` not writing to history
  ([#1749](https://github.com/pry/pry/issues/1749))

#### Other changes

* Deprecated the `Data` constant to match Ruby 2.5 in the `ls` command
  ([#1731](https://github.com/pry/pry/pull/1731))
