Yes, it appears that the two cases are treated differently:
1) foo/**/*.py:  the shell expands the **, and interprets it the same
as "*",  so foo/**/*.py means any python file exactly one directory
deeper than foo
2) /**.py: the shell ignores this and passes it straight to Git.

So I guess the missing error message I reported originally is
logically correct in a kind of convoluted way: the ** is actually
matching real files (just not the ones you expected) and they don't
have any changes, so you don't get any output.

(Whether or not it makes sense for Git to produce identical output in
the case of both adding files with changes, and doing nothing at all,
is a debate I probably shouldn't start...)

Looks like I need a newer version of Bash.

In any case, it looks like Git does support some ** globbing natively.
I'm curious about the rules for that. They don't seem to be documented
in the git man page (http://schacon.github.com/git/user-manual.html).
