Re: [PATCH v2] Fix fetch/pull when run without --update-head-ok

Some confusing tutorials suggested that it would be a good idea to fetch
into the current branch with something like this:

	git fetch origin master:master

(or even worse: the same command line with "pull" instead of "fetch").
While it might make sense to store what you want to pull, it typically
is plain wrong when the current branch is "master".

As noticed by Junio, this behavior should be triggered by _not_ passing
the --update-head-ok option, but somewhere along the lines we lost that
behavior.

NOTE: this patch does not completely resurrect the original behavior
without --update-head-ok: the check for the current branch is now _only_
performed in non-bare repositories.
