of the original repository, we forgot to take the alternates the original

Added -m and -M flags for git-cvsimport to detect merge commits in cvs.
While this trusts the commit message, in repositories where merge commits
indicate 'merged from FOOBRANCH' the import works surprisingly well.

Even if some merges from CVS are bogus or incomplete, the resulting
branches are in better state to go forward (and merge) than without any
merge detection.

I track a CVS project which has a branch with a '/' in the branch name.
Since git wants the branch name to be a file name at the same time,
substitute that character to a '-' by default (override with "-s <subst>").

are completely different :-)

This fixes up usage of ".." (without an ending slash) and "." (with or
without the ending slash) in the git diff family.

It also fixes pathspec matching for the case of an empty pathspec, since a
"." in the top-level directory (or enough ".." under subdirectories) will
result in an empty pathspec. We used to not match it against anything, but
it should in fact match everything.

We always show the diff as an absolute path, but pathnames to diff are
taken relative to the current working directory (and if no pathnames are
given, the default ends up being all of the current working directory).

Note that "../xyz" also works, so you can do

	cd linux/drivers/char
	git diff ../block

and it will generate a diff of the linux/drivers/block changes.

Because there is no reason not to, and this makes things a bit
safer when running "git prune".

[jc: I do not necessarily agree with the reasoning of the
original author that it is a good way to keep "git prune" from
stomping on objects to have a symlink that points at .git/refs
of the repository A in the .git/refs of the repository B when
repository A borrows object database from repository B.  For one
thing, the object database that everybody borrows objects from
may not even have its own .git/refs hierarchy.  Come to think of
it, maybe we should disallow symlink inside .git/refs hierarchy;
we update the files there by creat/rename pair, so having
symlinks would not work anyway when you do anything that would
update them.]

Early versions of git-cvsimport defaulted to using preexisting keyword
expansion settings. This change preserves compatibility with existing cvs
imports and allows new repository migrations to kill keyword expansion.

After exploration of the different -k modes in the cvs protocol, we use -kk
which kills keyword expansion wherever possible. Against the protocol
spec, -ko and -kb will sometimes expand keywords.

Should improve our chances of detecting merges and reduce imported
repository size.

The git-cvsimport-script had a copule of small bugs that prevented me
from importing a big CVS repository.

The first was that it didn't handle removed files with a multi-digit
primary revision number.

The second was that it was asking the CVS server for "F" messages,
although they were not handled.

I also updated the documentation for that script to correspond to
actual flags.

* Allow spaces in filenames.

The recent change to give the multiple commit message source was not
carrying over the authorship information from -C/-c commits correctly.
The export of the environment variable happens only in the subprocess,
not the main process that eventually runs git-commit-tree.

The right fix might be to teach git-commit-script to grok the From:
and Date: lines at the beginning of the commit message just like
git-applymbox knows how, but this has to do until that enhancement
happens.

Right now git causes ash to choke on the redundant shift on line two.

Reduces the number of system calls git makes just to do a usage

Presents a standard usage statement, and pretty prints the available
commands in a form that does not scroll off small terminals.
