X-Git-Tag: v1.8.4-rc1~16^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=e78095c3d05712b9479211bcc7faa1d8e9bf2723;p=git

git-completion.bash: replace zsh notation that breaks bash 3.X

50c5885e (git-completion.bash: replace zsh notation that breaks bash
3.X, 2013-01-18) fixed a zsh-ism introduced earlier to append to an
array, which older versions of bash (3.0) did not grok.  This was
again broken by 734b2f05 (completion: synchronize zsh wrapper,
2013-05-08).

Cherry-pick the fix again to let those with older bash use the
completion script.
