I really hate to suggest this, but should it be more like:
if test -z "$FAKE_COMMAND_LIST"; then
__git_cmdlist() {
git help -a | egrep '^ [a-zA-Z0-9]'
}
else
__git_cmdlist() {
printf '%s' "$FAKE_COMMAND_LIST"
}
fi
That gives us a nice predictable starting point for actually testing the
completion code. The downside is that it doesn't let us test that we
remain compatible with the output of "help -a". But we could potentially
add a single, more liberal test (without $FAKE_COMMAND_LIST, but ready
to expect extra output) that checks that.

If I recall correctly, egrep is actually more portable than "grep -E"
(and it is already in use, so I think we are OK). I agree on the rest,
though. :)
