Good to know.

BTW I looked at the completion script [1] and see that recent
effort to help automate more in git-completion.bash might help there
too. I notice a lot of options and help text hard coded there, if
someone can explain to me how uses those, maybe I can change
git to export something suitable for to use too [2].

For example with latest git (in 'master') doing this

    ./git add --git-completion-helper

gives you the list of all options of "git add". Giving the help text
for each option is definitely possible (I just didn't see any use for
it until I looked at zsh/fish completion scripts) and maybe more in
the future.

[2] But then if your script has to work with old git versions too then
this is a moot point.
