'\n' from the end of the prior log; during this scan the last '>'
is remembered to improve performance (rather than scanning forward
to it).

use its new sha1 value if the date matches exactly; otherwise we
leave the passed in sha1 alone as it already contains the current
value of the ref.  This way lookups of dates later than the log
end to stick with the current ref value in case the ref was updated
without logging.

If it looks like someone changed the ref without logging it and we
are going to return the sha1 which should have been valid during

missing and thus their query result may not be accurate.  The check

of the filenames, and do the "exec_grep()" flush call if it's bigger than

Allow one-way tree merge to remove old files

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.

This adds parsing of -U and --unified, both with an optional numeric

git diff --unified=5

something silly like

git config syntax updates

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,
