zsh-syntax-highlighting: update to 0.8.0.

# Changes in 0.8.0

This is a stable bugfix and feature release.  Major new features and changes include:

## Changes fixed as part of the switch to zle-line-pre-redraw

The changes in this section were fixed by switching to a `zle-line-pre-redraw`-based
implementation.

Note: The new implementation will only be used on future zsh releases,
numbered 5.8.1.1 and newer, due to interoperability issues with other plugins
(issues #418 and #579).  The underlying zsh feature has been available since
zsh 5.3.

Whilst under development, the new implementation was known as the
"feature/redrawhook" topic branch.

- Fixed: Highlighting not triggered after popping a buffer from the buffer stack
  (using the `push-line` widget, default binding: `M-q`)
  [#40]

- Fixed: Invoking completion when there were no matches removed highlighting
  [#90, #470]

- Fixed: Two successive deletes followed by a yank only yanked the latest
  delete, rather than both of them
  [#150, #151, #160; cf. #183]

- Presumed fixed: Completing `$(xsel)` results in an error message from `xsel`,
  with pre-2017 versions of `xsel`.  (For 2017 vintage and newer, see the issue
  for details.)
  [#154]

- Fixed: When the standard `bracketed-paste-magic` widget is in use, pastes were slow
  [#295]

- Fixed: No way to prevent a widget from being wrapped
  [#324]

- Fixed: No highlighting while cycling menu completion
  [#375]

- Fixed: Does not coexist with the `IGNORE_EOF` option
  [#377]

- Fixed: The `undefined-key` widget was wrapped
  [#421]

- Fixed: Does not coexist with the standard `surround` family of widgets
  [#520]

- Fixed: First completed filename doesn't get `path` highlighting
  [#632]

# Changes in 0.8.0-alpha1-pre-redrawhook

## Notice about an improbable-but-not-impossible forward incompatibility

Everyone can probably skip this section.

The `master` branch of zsh-syntax-highlighting uses a zsh feature that has not
yet appeared in a zsh release: the `memo=` feature, added to zsh in commit
zsh-5.8-172-gdd6e702ee (after zsh 5.8, before zsh 5.9).  In the unlikely event
that this zsh feature should change in an incompatible way before the next
stable zsh release, set `zsh_highlight__memo_feature=0` in your .zshrc files to
disable use of the new feature.

z-sy-h dogfoods the new, unreleased zsh feature because that feature was
added to zsh at z-sy-h's initiative.  The new feature is used in the fix
to issue #418.

## Incompatible changes:

- An unsuccessful completion (a <kbd>⮀ Tab</kbd> press that \ 
doesn't change the
  command line) no longer causes highlighting to be lost.  Visual feedback can
  alternatively be achieved by setting the `format` zstyle under the `warnings`
  tag, for example,

        zstyle ':completion:*:warnings' format '%F{red}No matches%f'

    Refer to the [description of the `format` style in `zshcompsys(1)`]
    [zshcompsys-Standard-Styles-format].

  revision zsh-5.8-172-gdd6e702ee or newer is also fine.)
