The function fgets() has a big problem with NUL characters: it reads
them, but nobody will know if the NUL comes from the file stream, or
was appended at the end of the line.

So implement a custom read_line_with_nul() function.

This patch renames the following documents and at the same time converts
them to the man page format:

cvs-migration.txt -> gitcvs-migration.txt
tutorial.txt      -> gittutorial.txt
tutorial-2.txt    -> gittutorial-2.txt

These new man pages are put in section 7, and other documents that reference
the above ones are change accordingly.

  rev-parse --symbolic-full-name: don't print '^' if SHA1 is not a ref

The intention of --symbolic-full-name is to not print anything if a
revision is not an exact ref. But this command:

    $ git-rev-parse --symbolic-full-name --not master~1

still emitted a sole '^' to stdout (provided that there's no other ref at
master~1). This fixes it.

Output format from "git add -n $path" lists path to blobs that are going
to be added on a single line, separated with SP.  On the other hand, the
suggested "git add -u -n" shows one path per line, like "add '<file>'\n".
Of course, these two are inconsistent.

Plain "git add -n" can afford to only say names of paths, as all it does
is to add (update).  However, "git add -u" needs to be able to express
"remove" somehow.  So if we need to have them formatted the same way, we
need to unify with the "git add -n -u" format.  Incidentally, this is
consistent with how 'update-index' says it.

This changes the output from "git add -n $paths" but as a general
principle, output from Porcelain commands is a fair game for improvements
and not for script consumption.

The first test in this series tests "git clone -l -s --reference B A C",
where repo B is a superset of repo A (A has one commit, B has the same
commit plus another). In this case, all objects to be cloned are already
present in B.

However, we should also test the case where the "--reference" repo is a
_subset_ of the source repo (e.g. "git clone -l -s --reference A B C"),
i.e. some objects are not available in the "--reference" repo, and will
have to be found in the source repo.
