Expand the history-browsing section of the tutorial a bit, in part to
address Junio's suggestion that we mention "git grep" and Linus's
complaint that people are missing the flexibility of the commandline
interfaces for selecting commits.

This reads a little more like a collection of examples than a
"tutorial", but maybe that's what people need at this point.

Actually, it is a diff option now, so you can say

	git diff --check

to ask if what you are about to commit is a good patch.

[jc: this also would work for fmt-patch, but the point is that
 the check is done before making a commit.  format-patch is run
 from an already created commit, and that is too late to catch
 whitespace damaged change.]

Handle the -S option when passed to git log such that only the
appropriate commits are displayed.  Also per Junio's comments, do
the same for "--diff-filter", so that it too can be used as an option
to git log.  By default no patch or diff information is displayed.

This cleans up and libifies the "git update-index --[really-]refresh"
functionality. This will be eventually required for eventually doing the
"commit" and "status" commands as built-ins.

It really just moves "refresh_index()" from update-index.c to
read-cache.c, but it also has to change the calling convention so that the
function uses a "unsigned int flags" argument instead of various static
flags variables for passing down the information about whether to be quiet
or not, and allow unmerged entries etc.

That actually cleans up update-index.c too, since it turns out that all
those flags were really specific to that one function of the index update,
so they shouldn't have had file-scope visibility even before.

Since large quilt trees like -mm can easily have patches
without clear authorship information, add a --dry-run
option to make the problem patches easy to find.
Signed-off-by: NJunio C Hamano <junkio@cox.net>

Importing a quilt patch series into git is not very difficult
but parsing the patch descriptions and all of the other
minutia take a bit of effort to get right, so this automates it.

Since git and quilt complement each other it makes sense
to make it easy to go back and forth between the two.

If a patch is encountered that it cannot derive the author
from the user is asked.

This was surprisingly easy. The diff is truly minimal: rename "main()" to
"cmd_rev_list()" in rev-list.c, and rename the whole file to reflect its
new built-in status.

Gitk wants to use git-diff-tree as a filter to tell it which ids from
a given list affect a set of files or directories.  We don't want to
fork and exec a new git-diff-tree process for each batch of ids, since
there could be a lot of relatively small batches.  For example, a
batch could contain as many ids as fit in gitk's headline display
window, i.e. 20 or so, and we would be processing a new batch every
time the user scrolls that window.

The --stdin flag to git-diff-tree is suitable for this, but the main
difficulty is that the output of git-diff-tree gets buffered and
doesn't get sent until the buffer is full.

This provides a way to get git-diff-tree to flush its output buffers.
If a blank line is supplied on git-diff-tree's standard input, it will
flush its output buffers and then accept further input.

Of course, it still ignores the fact that not all grep's support some of
the flags like -F/-L/-A/-C etc, but for those cases, the external grep
itself will happily just say "unrecognized option -F" or similar.

So with this change, "git grep" should handle all the flags the native
grep handles, which is really quite fine. We don't _need_ to expose
anything more, and if you do want our extensions, you can get them with
"--uncached" and an up-to-date index.

No configuration necessary, and we automatically take advantage of any
native grep we have, if possible.

Some implementations do not know what to do with -H; define
NO_H_OPTION_IN_GREP when you build git if your grep lacks -H.

Most of the time, it can be worked around by prepending
/dev/null to the argument list, but that causes -L and -c to
slightly misbehave (they both expose /dev/null is given), so
when these options are given, do not run external grep that does
not understand -H.

When a merge results in a creation of a path that did not exist
in HEAD, and if you already have that path on the working tree,
because the index has not been told about the working tree file,
read-tree happily removes it.  The issue was brought up by Santi
Béjar on the list.
