[PATCH] git-completion.zsh: do not clobber complete()

[PATCH] git-completion.zsh: do not clobber complete()

[Mark Lodato]

Previously, git-completion.zsh redefined complete() to make __git_complete()
a no-op. This broke zsh's built-in bash completion compatibility layer
(bashcompinit), which defines its own complete().

Sadly, since there is no way in zsh to restore the original defintion of
complete() after bash-completion.bash is sourced, we must pass in a flag to
git-completion.bash to change its behavior.

How exactly? I'm testing this and I don't see any problems. I run
'type -f _complete' and I get bashcompinit's complete, and the internal
_complete() function is used only by the _git completion.

How have you configured this completion? Are you using the recommended
instructions?

Ah, it's complete(), not _complete(). I see the problem and I'll propose
a similar patch.
