This reminded me to a mini-series collecting dust in my git repo,
which converts a few similar var=$var$something constructs to use the
+= append operator instead.

Is the benefit of rewriting it to var+=$something large enough to
worry about the below?

That way we can get rid of a subshell in __gitcomp(), which means one
less fork() during every command or option completion for Windows
folks.  We can also get rid of two subshells during loading the
completion script.

And I would spare myself from a couple of merge conflicts, too ;)

Now, Bash supports this += append operator since v3.1
(bash-3.1-alpha1, to be exact), which is around since July 2005, if I
can trust the mtime at ftp://ftp.cwru.edu/pub/bash/.  MSysgit ships
v3.1 so it already supports this, too.  So, what is the oldest Bash
version we care about for completion?
