I tried to jug my memory in this area a bit by reading the relevant
code.  For non-wildcard refspec, e.g. with

    [remote "origin"]
	url = ../git.git/
	fetch = master:remotes/origin/master
	tagopt = --no-tags

you'd get

    $ git fetch -v
    From ../git
     * [new branch]            master     -> origin/master
    $ git for-each-ref
    2e36527f23b7f6ae15e6f21ac3b08bf3fed6ee48 commit	refs/remotes/origin/master

It all happens inside remote.c::get_fetch_map(), I think.

Thanks.
