Subject: bash: Add space after unique command name is completed.
X-Git-Tag: v1.5.0-rc4~56
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=72e5e989b8c22dc6dd2b4f889d5d0dabf698b387;p=git.git

bash: Add space after unique command name is completed.

Because we use the nospace option for our completion function for
the main 'git' wrapper bash won't automatically add a space after a
unique completion has been made by the user.  This has been pointed
out in the past by Linus Torvalds as an undesired behavior.  I agree.

We have to use the nospace option to ensure path completion for
a command such as `git show` works properly, but that breaks the
common case of getting the space for a unique completion.  So now we
set IFS=$'\n' (linefeed) and add a trailing space to every possible
completion option.  This causes bash to insert the space when the
completion is unique.
