2dee060968 Improve build: add <unistd.h> and use -O2 instead of -O3
(Nobody should use -O3. It just makes bad inlining decisions).

4990aadc4c Speed up index file writing by chunking it nicely.
No point in making 17,000 small writes when you can make just
a couple of hundred nice 8kB writes instead and save a lot

ad4e9ce4f9 [PATCH] make dotest more amenable to commit message editing
This makes "dotest" a lot nicer to sue, especially for people who were
used to editing the commit comments after-the-fact in BK, which git
doesn't apply. 

he syntax is

	dotest [-q] mailbox [signoff]

so the command line operates exactly as you're used to.  If you supply
the -q it will query before applying (I also added the [a]pply all the
rest option).  If the signoff file is absent, no signoff line gets
added. 

There's also one addition in this:  a checkout-cache line.  I added that
for poor saps like me whose laptop takes minutes to checkout a full
build tree, so I can run dotest in a directory with no checked out
files.

abdb007d1f Make "diff-tree" take commit objects too, like "diff-cache" does.
Sometimes it's just easier to not have to look up the "commit"->"tree"
translation by hand first. It's trivial to do inside diff-tree, and
it's just being polite.

e74f8f6aa7 Add "diff-cache" helper program to compare a tree (or commit) with
the current cache state and/or working directory.

Very useful to see what has changed since the last commit, either in
the index file or in the whole working directory.

Also very possibly very buggy. Matching the two up is not entirely
trivial.

0a9ea85000 [PATCH] SCSI trees, merges and git status
Doing the latest SCSI merge exposed two bugs in your merge script:

b70070f020 [PATCH] provide better committer information to commit-tree.c
Here's a small patch to commit-tree.c that does two things:
	- allows the committer email address and name to be overridden
	  by environment variables (if you don't like the environment
	  variable names I've used (COMMIT_AUTHOR_NAME,
	  COMMIT_AUTHOR_EMAIL), feel free to change them.)
	- provide the proper domainname to the author/committer email
	  address (otherwise, my address was only showing up as from the
	  hostname.)

This allows people to set sane values for the commit names and email
addresses, preventing odd, private hostnames and domains from being
exposed to the world.

This introduces the concept of git "library" objects that

839a7a06f3 Add the simple scripts I used to do a merge with content conflicts.
They sure as hell aren't perfect, but they allow you to do:

	./git-pull-script {other-git-directory}

to do the initial merge, and if that had content clashes, you do

	merge-cache ./git-merge-one-file-script -a

which tries to auto-merge. When/if the auto-merge fails, it will
leave the last file in your working directory, and you can edit
it and then when you're happy you can do "update-cache filename"
on it. Re-do the merge-cache thing until there are no files left
to be merged, and now you can write the tree and commit:

	write-tree
	commit-tree .... -p $(cat .git/HEAD) -p $(cat .git/MERGE_HEAD)

and you're done.

a4b7dbef4e [PATCH] fix bug in read-cache.c which loses files when merging a tree
I noticed this when I tried a non-trivial scsi merge and checked the
results against BK.  The problem is that remove_entry_at() actually
decrements active_nr, so decrementing it in add_cache_entry() before
calling remove_entry_at() is a double decrement (hence we lose cache
entries at the end).
