This patch rewrites the general description yet again, first clarifying
the high-level concept, mentioning the difference to remotes and using
the subtree merge strategy, then getting to the details about tree
entries and .gitmodules file.

The patch also makes few smallar grammar fixups within the rest of the
description and clarifies how does 'init' relate to 'update --init'.

This adds only the minimum necessary to keep git pull/merge's diffstat from
wrapping. Notably absent is support for the K (erase) operation, and support
for POSIX write.

The function has to do three small and independent tasks, but all of them
were crammed into a single loop. This rewrites the function entirely by
unrolling these tasks.

We also now use is_dir_sep(c) instead of c == '/' to increase portability.

Commit 5b8e6f85 introduced stubs for three functions that make no sense
for git-shell. But those stubs defined libgit.a functions a second time
so that a linker can complain.

Now git-shell is only linked to a subset of libgit.a.

Scriptlets used form inside this test began with hardcoded "#!/bin/sh".
By setting SHELL_PATH the user is already telling us that what the vendor
has in /bin/sh isn't POSIX enough, and we really should try to honor that
request.

verified that it fixes the issue on Solaris 9.

The original code relied on an insane definition of skip_prefix() that
returned an empty string for a NULL input and returned the original if the
given "prefix" is not a prefix at all (it would have been justifiable if
it were called "come_up_with_a_short_name_to_report_ref()" or something,
though).  In any case, when we replaced it with a more saner definition of
the function whose behaviour is true to its name, its callers needed to be
adjusted but the conversion missed one call site.

This introduces a helper function "abbrev_ref()" whose purpose is to get a
full refname and its possible prefix and to strip the prefix part if it
matches, or refname itself in full if it doesn't.  This makes the callers
easier to read again.

Figuring out how submodules work conceptually is quite a bumpy
ride for a newcomer; the user manual helps (if one knows to actually
look into it), but the reference documentation should provide good
quick intro as well. This patch attempts to do that, with suggestions
from Heikki Orsila.

If the repo is empty, it is obvious that there are no common commits
when fetching from _anywhere_.

So there is no use in saying it in that case, and it can even be
annoying.  Therefore suppress the message unilaterally if the repository
is empty prior to the fetch.

When "rebase -i -p" tries to preserve merges of unrelated branches, it
lost some parents:

 - When you have more than two parents, the commit in the new history
   ends up with fewer than expected number of parents and this breakage
   goes unnoticed;

 - When you are rebasing a merge with two parents and one is lost, the
   command tries to cherry-pick the original merge commit, and the command
   fails.
