Fair enough.  I vaguely remembered this thread [1], that tried to add
'rm' back to the autocompletion after it was removed originally to try
and start the deprecation process.  Reading the thread again now
though it seems what you outline below to just not show "save" when
"git stash <TAB>" or "git stash s<TAB>" is typed makes more sense as a
step now.

I also notice that we never seemed to have taken any of the
suggestions made there (either adding 'rm' back to the completion
options, or going further in the deprecation process), though that's a
different topic :)

Thanks for the suggestions, I'll take a closer look at what could be
done, and will send a re-roll.
