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?

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?
