This patch clean up append_signoff() by moving specific code that
looks up for "^[-A-Za-z]+: [^@]+@" pattern into a function.

It also stops the primary search when the cursor oversteps
'buf + at' limit.

This patch changes slightly append_signoff() behaviour too. If we
detect any Signed-off-by pattern during the primary search, we
needn't to do a pattern research after.

The comment added says it all: if we have lost all references in a git
archive, git-fsck-objects should still work, so instead of dying it should
just notify the user about that condition.

This change was triggered by me just doing a "git-init-db" and then
populating that empty git archive with a pack/index file to look at it.
Having git-fsck-objects not work just because I didn't have any references
handy was rather irritating, since part of the reason for running
git-fsck-objects in the first place was to _find_ the missing references.

However, "--unreachable" really doesn't make sense in that situation, and
we want to turn it off to protect anybody who uses the old "git prune"
shell-script (rather than the modern built-in). The old pruning script
used to remove all objects that were reported as unreachable, and without
any refs, that obviously means everything - not worth it.

After a failed "git am" attempt:

	git apply --reject --verbose .dotest/patch

applies hunks that are applicable and leaves *.rej files the
rejected hunks, and it reports what it is doing.  With --index,
files with a rejected hunk do not get their index entries
updated at all, so "git diff" will show the hunks that
successfully got applied.

Without --verbose to remind the user that the patch updated some
other paths cleanly, it is very easy to lose track of the status
of the working tree, so --reject implies --verbose.

I noticed that I was looking at the kernel gitweb output at some point
rather than just do "git log", simply because I liked seeing the
simplified date-format, ie the "5 days ago" rather than a full date.

This adds infrastructure to do that for "git log" too. It does NOT add the
actual flag to enable it, though, so right now this patch is a no-op, but
it should now be easy to add a command line flag (and possibly a config
file option) to just turn on the "relative" date format.

The exact cut-off points when it switches from days to weeks etc are
totally arbitrary, but are picked somewhat to avoid the "1 weeks ago"
thing (by making it show "10 days ago" rather than "1 week", or "70
minutes ago" rather than "1 hour ago").

In the Windows world ZIP files are better supported than tar files.
Windows even includes built-in support for ZIP files nowadays.

git-zip-tree is similar to git-tar-tree; it creates ZIP files out of
git trees.  It stores the commit ID (if available) in a ZIP file comment
which can be extracted by unzip.

There's still quite some room for improvement: this initial version
supports no symlinks, calls write() way too often (three times per file)
and there is no unit test.

Change unpack_entry_gently and its helper functions to use offsets

If we're always incrementing both the offset and the pointer we
aren't gaining anything by keeping both.  Instead just use the
offset since that's what we were given and what we are expected

the pack in the future should partial mapping of very large packs
get implemented.
