This makes git-push refuse pushing into a non-bare repository to update
the current branch by default. To help people who are used to be able to
do this (and later "reset --hard" it in some other way), an error message
is issued when this refusal is triggered, instructing how to resurrect the
old behaviour.
Hosting sites that do not give the users direct access to customize their
repositories (e.g. repo.or.cz, gitorious, github etc.) may further want to
explicitly set the configuration variable to "refuse" for their customers'
repositories.

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". This should only be
allowed when (an incorrect) "git pull origin master:master" tries to work
around by giving --update-head-ok to underlying "git fetch", and otherwise
we should refuse it, but somewhere along the lines we lost that behavior.
The check for the current branch is now _only_ performed in non-bare
repositories, which is an improvement from the original behaviour.
Some newer tests were depending on the broken behaviour of "git fetch"
this patch fixes, and have been adjusted.

When pushing to overwrite a ref that points at a commit we do
not even have, the recent "terse push" patch tried to get a
unique abbreviation for the non-existent (from our point of
view) object, which resulted in strcpy(buf, NULL) and
segfaulted.
