completions/git: Only use first line of alias as the description

Browse source 
This was a weird one. We split the aliases correctly even with
multiple lines, but then broke it all again when we just printed the
description.

Note that it would be possible to use `string split0` here, but since
anything longer than a line is likely too long for a description
anyway we don't bother.

Fixes #6946.
