Instead, we complain to the user and suggest that they explicitly
specify the remote and branch. We depend on the exit status of
git-symbolic-ref, so let's go ahead and document that.

When we are on a detached HEAD, there is no current branch.
There is no reason to leak the error messages to the end user
since this is a situation we expect to see.
This adds -q option to git-symbolic-ref to exit without issuing
an error message if the given name is not a symbolic ref.
By the way, with or without this patch, there currently is no
good way to tell failure modes between "git symbolic-ref HAED"
and "git symbolic-ref HEAD". Both says "is not a symbolic ref".
We may want to do something about it.

My prior version of git-describe ran very slowly on even reasonably
sized projects like git.git and linux.git as it tended to identify
a large number of possible tags and then needed to generate the
revision list for each of those tags to sort them and select the
best tag to describe the input commit.
All we really need is the number of commits in the input revision
which are not in the tag. We can generate these counts during
the revision walking and tag matching loop by assigning a color to
each tag and coloring the commits as we walk them. This limits us
to identifying no more than 26 possible tags, as there is limited
space available within the flags field of struct commit.
The limitation of 26 possible tags is hopefully not going to be a
problem in real usage, as most projects won't create 26 maintenance
releases and merge them back into a development trunk after the
development trunk was tagged with a release candidate tag. If that
does occur git-describe will start to revert to its old behavior of
using the newer maintenance release tag to describe the development
trunk, rather than the development trunk's own tag. The suggested
workaround would be to retag the development trunk's tip.
However since even 26 possible tags can take a while to generate a
description for on some projects I'm defaulting the limit to 10 but
offering the user --candidates to increase the number of possible
matches if they need a more accurate result. I specifically chose
10 for the default as it seems unlikely projects will have more
than 10 maintenance releases merged into a development trunk before
retagging the development trunk, and it seems to perform about the
same on linux.git as v1.4.4.4 git-describe.
A large amount of debugging information was also added during
the development of this change, so I've left it in to be toggled
on with --debug. It may be useful to the end user to help them
understand why git-describe took one particular tag over another.

and this change makes it so. I think level 3 is probably pointless

The goals are:
- Readable from beginning to end in order without having read
any other git documentation beforehand.
- Helpful section names and cross-references, so it's not too
hard to skip around some if you need to.
- Organized to allow it to grow much larger (unlike the
tutorials)
It's more liesurely than tutorial.txt, but tries to stay focused on
practical how-to stuff. It adds a discussion of how to resolve merge
conflicts, and partial instructions on setting up and dealing with a
public repository.
I've lifted a little bit from "branching and merging" (e.g., some of the
discussion of history diagrams), and could probably steal more if that's
OK. (Similarly anyone should of course feel free to reuse bits of this
if any parts seem more useful than the whole.)
There's a lot of detail on managing branches and using git-fetch, just
because those are essential even to people needing read-only access
(e.g., kernel testers). I think those sections will be much shorter
once the new "git remote" command and the disconnected checkouts are
taken into account.
I do feel bad about adding yet another piece of documentation, but I we
need something that goes through all the basics in a logical order, and
I wasn't seeing how to grow the tutorials into that.
