Log Message:
Update devel/lua-penlight to 1.3.2.

## 1.3.2

### Changes

  - now works and passes tests with Lua 5.3
  - utils.import will NOT override global symbols (import 'math' caused global \ 
type() to be clobbered)
  - Updated pl.dir.file_op to return true on success and false on failure...
  - workaround for issues with pl.lapp with amalg.lua - will look at global \ 
LAPP_SCRIPT if arg[0] is nil

### Fixes

  - func was broken: do NOT use ipairs to iterate if __index is overriden!
  - issue #133 pretty.read (naively) confused by unbalanced brackets
  - xml attribute underscore fix for simple parser
  - Fix path.normpath
  - lexer: fix parsing block comments/string. fix hang on empty string.
  -  Fixed utils.execute returning different values for Lua 5.1 and Lua 5.2
  - Issue #97; fixed attempt to put a month into a day
  -  problem with tablex.count_map with custom comparison

### Features

  -  Add Python style url module for quote and unquote.
  -  stringx.quote_string, which scans for embedded long-string quote matches \ 
and escapes them by creating a long-string quote.
  -  issue #117: tablex.range now works with decreasing numbers, consistent with \ 
numerical for loop
  -  utils.import will NOT override global symbols (import 'math' caused global \ 
type() to be clobbered)
  - issue #125: DOCTYPE ignored in xml documents as well
  - Allow XML tostring() function to customize the default prefacing with \ 
<?xml...>
  - More Robust Quoted Strings
  - lapp: improved detection of unsupported short flags

## 1.3.0

### Changes

  - class: RIP base method - not possible to implement correctly
  - lapp: short flags can now always be followed directly by their value, for \ 
instance,
`-I/usr/include/lua/5.1`
  - Date: new explicit `Date.Interval` class; `toUTC/toLocal` return new object; \ 
`Date.__tostring`
always returns ISO 8601 times for exact serialization.  `+/-` explicit \ 
operators. Date objects
are explicitly flagged as being UTC or not.

### Fixes

  - class: super method fixed.
  - Date: DST is now accounted for properly.
  - Date: weekday calculation borked.

### Features

  - All tests pass with no-5.1-compatible Lua 5.2; now always uses `utils.load` and
`utils.unpack` is always available.
  - types: new module containing `utils.is_xxx` methods plus new `to_bool`.
  - class: can be passed methods in a table (see `test=klass.lua`). This is
particularly convenient for using from Moonscript.
  - general documentation improvements, e.g `class`

## 1.2.1

### Changes

  - utils.set(get)fenv always defined (_not_ set as globals for 5.2 anymore!).
    These are defined in new module pl.compat, but still available through utils.
  - class.Frodo now puts 'Frodo' in _current environment_

### Fixes

  - lapp.add_type was broken (Pete Kazmier)
  - class broke with classes that redefined __newindex
  - Set.isdisjoint was broken because of misspelling; default ctor Set() now \ 
works as expected
  - tablex.transform was broken; result now has same keys as original \ 
(CoolistheName007)
  - xml match not handling empty matches (royalbee)
  - pl.strict: assigning nil to global declares it, as God intended. (Pierre Chapuis)
  - tests all work with pl.strict
  - 5.2 compatible load now respects mode
  - tablex.difference thought that a value of `false` meant 'not present' \ 
(Andrew Starke)

### Features

  - tablex.sort(t) iterates over sorted keys, tablex.sortv(t) iterates over \ 
sorted values (Pete Kazmier)
  - tablex.readonly(t) creates a read-only proxy for a table (John Schember)
  - utils.is_empty(o) true if o==nil, o is an empty table, or o is an empty \ 
string (John Schember)
  - utils.executeex(cmd,bin) returns true if successful, return code, plus \ 
stdout and stderr output as strings. (tieske)
  - class method base for calling inherited methods (theypsilon)
  - class supports pre-constructor _create for making a custom self (used in pl.List)
  - xml HTML mode improvements - can parse non-trivial well-formed HTML documents.
    xml.parsehtml is a parse function, no longer a flag
  - if a LOM document has ordered attributes, use these when stringifying
  - xml.tostring has yet another extra parm to force prefacing with <?xml...>
  - lapp boolean flags may have `true` default
  - lapp slack mode where 'short' flags can be multi-char
  - test.asserteq etc take extra arg, which is extra level where error must be \ 
reported at
  - path.currentdir,chdir,rmdir,mkdir and dir as alias to lfs are exported; no \ 
dependencies on luafilesystem outside pl.path, making it easier to plug in \ 
different implementations.
