The "-u" flag means "update the working tree files", but to
other types of merges, it also implies "I want to keep my local
changes" -- because they prevent local changes from getting lost
by using verify_uptodate. The one-way merge is different from
other merges in that its purpose is opposite of doing something
else while keeping unrelated local changes. The point of
one-way merge is to nuke local changes. So while it feels
somewhat wrong that this actively loses local changes, it is the
right thing to do.

mutt, gnus, pine, mailrc formats should be supported.
Testing and feedback for correctness and completeness of all formats
and support for additional formats would be good.
Nested expansions are also supported.
More than one alias file to be used.
All alias file formats must still of be the same type, though.
Two git repo-config keys are required for this
(as suggested by Ryan Anderson):
sendemail.aliasesfile = <filename of aliases file>
sendemail.aliasfiletype = (mutt|gnus|pine|mailrc)

It's not perfect, but it gets the "git grep some-random-string" down to
the good old half-a-second range for the kernel.
It should convert more of the argument flags for "grep", that should be
trivial to expand (I did a few just as an example). It should also bother
to try to return the right "hit" value (which it doesn't, right now - the
code is kind of there, but I didn't actually bother to do it _right_).
Also, right now it _just_ limits by number of arguments, but it should
also strictly speaking limit by total argument size (ie add up the length
of the filenames, and do the "exec_grep()" flush call if it's bigger than
some random value like 32kB).
But I think that it's _conceptually_ doing all the right things, and it
seems to work. So maybe somebody else can do some of the final polish.

When renaming leading/a/filename to leading/b/filename (and
"filename" is sufficiently long), we tried to squash the rename
to "leading/{a => b}/filename". However, when "/a" or "/b" part
is empty, we underflowed and tried to print a substring of
length -1.

Now that the one-way merge strategy does the right thing wrt files that do
not exist in the result, just remove all the random crud we did in "git
reset" to do this all by hand.
Instead, just pass in "-u" to git-read-tree when we do a hard reset, and
depend on git-read-tree to update the working tree appropriately.
This basically means that git reset turns into
# Always update the HEAD ref
git update-ref HEAD "$rev"
case "--soft"
# do nothing to index/working tree
case "--hard"
# read index _and_ update working tree
git-read-tree --reset -u "$rev"
case "--mixed"
# update just index, report on working tree differences
git-read-tree --reset "$rev"
git-update-index --refresh
which is what it was always semantically doing, it just did it in a
rather strange way because it was written to not expect git-read-tree to
do anything to the working tree.

For some random reason (probably just because nobody noticed), the one-way
merge strategy didn't mark deleted files as deleted, so if you used
git-read-tree -m -u <newtree>
it would update the files that got changed in the index, but it would not
delete the files that got deleted.
This should fix it, and I can't imagine that anybody depends on the old
strange "update only existing files" behaviour.

We used to parse "-U" and "--unified" as part of the GIT_DIFF_OPTS
environment variable, but strangely enough we would _not_ parse them as
part of the normal diff command line (where we only accepted "-u").
This adds parsing of -U and --unified, both with an optional numeric
argument. So now you can just say
git diff --unified=5
to get a unified diff with a five-line context, instead of having to do
something silly like
GIT_DIFF_OPTS="--unified=5" git diff -u
(that silly format does continue to still work, of course).

This updates the hierarchical section name syntax to
[section<space>+"<randomstring>"]
where the only rule for "randomstring" is that it can't contain a newline,
and if you really want to insert a double-quote, you do it with \".
It turns that into the section name "secion.randomstring". The
"section" part is still case insensitive, but the "randomstring"
part is case sensitive.
So you could use this for things like
[email "torvalds@osdl.org"]
name = Linus Torvalds
if you wanted to do the "email->name" conversion as part of the config
file format (I'm not claiming that is sensible, I'm just giving it as an
insane example). That would show up as the association
email.torvalds@osdl.org.name -> Linus Torvalds
which is easy to parse (the "." in the email _looks_ ambiguous, but it
isn't: you know that there will always be a single key-name, so you find
the key name with "strrchr(name, '.')" and things are entirely
unambiguous).
Repo-config is updated to be able to parse the new format, and also
write things out in the new format.
[jc: rolled two patches from Linus and one fix-up from Sean into one,

insensitiveness of section base and variable and case sensitiveness

If the variable we need to store should go into a section
that currently only has a single variable (not matching
the one we're trying to insert), we will already be into
the next section before we notice we've bypassed the correct
location to insert the variable.
To handle this case we store the current location as soon
as we find a variable matching the section of our new
variable.
This breakage was brought up by Linus.

The offset of an object in the pack is recorded as a 4-byte integer
in the index file. When reading the offset from the mmap'ed index
in prepare_pack_revindex(), the address is dereferenced as a long*.
This works fine as long as the long type is four bytes wide. On
NetBSD/sparc64, however, a long is 8 bytes wide and so dereferencing
the offset produces garbage.
