[PATCH] Invoke "git gc --auto" from "git add" and "git fetch"

[Junio C Hamano <gitster@pobox.com>]

This makes the two commands to call "git gc --auto" when they
are done.

I earlier said that obvious candidates also include merge and
rebase, but these are lot less frequent operations compared to
add, and more importantly, in a normal workflow they would
almost always happen after "git fetch" is done.

In other words, if you are downstream developer, the automatic
invocation in "git fetch" will take care of things for you, and
otherwise if you do not have an upstream, you would be doing
your own development, so "git add" to add your changes will take
care of the auto invocation for you.

 * This is obviously a follow-up to the previous one that allows
   you to say "git gc --auto".  I somewhat feel dirty about
   calling cmd_gc() bypassing fork & exec from "git add",
   though...
