Commit 13fc2c1 (remote: disallow some nonsensical option
combinations, 2011-03-30) made it impossible to use "remote
add -t foo --mirror". The argument was that specifying
specific branches is useless because:
1. Push mirrors do not want a refspec at all.
2. The point of fetch mirroring is to use a broad refspec
like "refs/*", but using "-t" overrides that.
Point (1) is valid; "-t" with push mirrors is useless. But
point (2) ignored another side effect of using --mirror: it
fetches the refs directly into the refs/ namespace as they
are found upstream, instead of placing them in a
separate-remote layout.
So 13fc2c1 was overly constrictive, and disallowed
reasonable specific-branch mirroring, like:
git remote add -t heads/foo -t heads/bar --mirror=fetch
which makes the local "foo" and "bar" branches direct
mirrors of the remote, but does not fetch anything else.
This patch restores the original behavior, but only for
fetch mirrors.

git-remote currently has one option, "--mirror", which sets
up mirror configuration which can be used for either
fetching or pushing. It looks like this:
[remote "mirror"]
url = wherever
fetch = +refs/*:refs/*
mirror = true
However, a remote like this can be dangerous and confusing.
Specifically:
1. If you issue the wrong command, it can be devastating.
You are not likely to "push" when you meant to "fetch",
but "git remote update" will try to fetch it, even if
you intended the remote only for pushing. In either
case, the results can be quite destructive. An
unintended push will overwrite or delete remote refs,
and an unintended fetch can overwrite local branches.
2. The tracking setup code can produce confusing results.
The fetch refspec above means that "git checkout -b new
master" will consider refs/heads/master to come from
the remote "mirror", even if you only ever intend to
push to the mirror. It will set up the "new" branch to
track mirror's refs/heads/master.
3. The push code tries to opportunistically update
tracking branches. If you "git push mirror foo:bar",
it will see that we are updating mirror's
refs/heads/bar, which corresponds to our local
refs/heads/bar, and will update our local branch.
To solve this, we split the concept into "push mirrors" and
"fetch mirrors". Push mirrors set only remote.*.mirror,
solving (2) and (3), and making an accidental fetch write
only into FETCH_HEAD. Fetch mirrors set only the fetch
refspec, meaning an accidental push will not force-overwrite
or delete refs on the remote end.
The new syntax is "--mirror=<fetch|push>". For
compatibility, we keep "--mirror" as-is, setting up both
types simultaneously.

(Just like we did for documentation already)
In the process, we change "non-remote branch" to "branch outside the
refs/remotes/ hierarchy" to avoid the ugly "non-remote-tracking branch".
The new formulation actually corresponds to how the code detects this
case (i.e. prefixcmp(refname, "refs/remotes")).
Also, we use 'remote-tracking branch' in generated merge messages (by
merge an fmt-merge-msg).

This test is supposed to check that git-remote correctly refuses to delete
all URLS for the specified remote which match the '.*' regular expression.
Since the '*' was not protected, it was interpreted by the shell as a file
glob and expanded before being passed to git-remote. The call to
git-remote still exited non-zero in this case, and the overall test still
passed, but it exited non-zero because git-remote was passed the incorrect
number of arguments, not for the reason it was supposed to fail.

Brandon Casey noticed that t5505 had accidentally broken its && chain,
hiding inconsistency between the code that writes the warning to the
standard output and the test that expects to see the warning on the
standard error, which was introduced by f8948e2 (remote prune: warn
dangling symrefs, 2009-02-08).
It turns out that the issue is deeper than that. After f8948e2, a symref
that is dangling is marked with a NULL sha1, and the idea of using NULL
sha1 to mean a deleted ref was scrapped, but somehow a follow-up eafb452
(do_one_ref(): null_sha1 check is not about broken ref, 2009-07-22)
incorrectly reorganized do_one_ref(), still thinking NULL sha1 is never
used in the code.
Fix this by:
- adopt Brandon's fix to t5505 test;
- introduce REF_BROKEN flag to mark a ref that fails to resolve (dangling
symref);
- move the check for broken ref back inside the "if we are skipping
dangling refs" code block.

make this clearer now by displaying the first one prefixed with "Fetch
URL", and all "url"s (or, if present, all "pushurl"s) prefixed with
"Push URL".
Example with "one" having one url, "two" two urls, "three" one url and
one pushurl (URL part only):
* remote one
Fetch URL: hostone.com:/somepath/repoone.git
Push URL: hostone.com:/somepath/repoone.git
* remote two
Fetch URL: hosttwo.com:/somepath/repotwo.git
Push URL: hosttwo.com:/somepath/repotwo.git

The existing output of "git remote show <remote>" with respect to push
ref specs is basically just to show the raw refspec. This patch teaches
the command to interpret the refspecs and show how each branch will be
pushed to the destination. The output gives the user an idea of what
"git push" should do if it is run w/o any arguments.
Example new output:
1a. Typical output with no push refspec (i.e. matching branches only)
$ git remote show origin
* remote origin
[...]
Local refs configured for 'git push':
master pushes to master (up to date)
next pushes to next (local out of date)
1b. Same as above, w/o querying the remote:
$ git remote show origin -n
* remote origin
[...]
Local ref configured for 'git push' (status not queried):
(matching) pushes to (matching)
2a. With a forcing refspec (+), and a new topic
(something like push = refs/heads/*:refs/heads/*):
$ git remote show origin
* remote origin
[...]
Local refs configured for 'git push':
master pushes to master (fast forwardable)
new-topic pushes to new-topic (create)
next pushes to next (local out of date)
pu forces to pu (up to date)
2b. Same as above, w/o querying the remote
$ git remote show origin -n
* remote origin
[...]
Local refs configured for 'git push' (status not queried):
master pushes to master
new-topic pushes to new-topic
next pushes to next

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.

On a local clone, "git clone" would use the fully DWIMmed path as the origin
URL in the resulting repo. This was slightly inconsistent with the case of a
remote clone where the _given_ URL was used as the origin URL (because the
DWIMming was done remotely, and was therefore not available to "git clone").
This behaviour caused problems when cloning a local non-bare repo with
relative submodule URLs, because these submodule URLs would then be resolved
against the DWIMmed URL (e.g. "/repo/.git") instead of the given URL (e.g.
"/repo").
This patch teaches "git clone" to use the _given_ URL - instead of the
DWIMmed path - as the origin URL. This causes relative submodule URLs to be
resolved correctly, as long the _given_ URL indicates the correct directory
against which the submodule URLs should be resolved.
The patch also updates a testcase that contained the old-style origin URLs.
