Gotcha.  A static list buried in git-completion.bash would be a maintenance
headache.  I can take a look at that some.

Would we also want to look at doing something similar with '--' option
completion, i.e. invoking the command with '-h' to get the usage and long
options, then building the completion list on that rather than the static
lists it uses now?  The one downside to that is that some completions
include trailing '=', which wouldn't be present in a usage list.
