This does not look like "add convenient function for auto-gc" nor "avoid
forking"; it is something else that is not explained.

Don't call this "gc".

It is hardcoded to perform a cheaper version "gc --auto" and nothing
else, and it may not even do that when configured not to.

I do not think the first parameter to this function is "cmd"
(abbreviation of "command") either.  Isn't it a configuration key to
tell if auto-gc is allowed, or something?

Other than that, it seems to be a nice change.
