Commit 682c7d2f (upload-pack: fix off-by-one depth calculation in shallow
clone) introduced a new check in get_shallow_commits to decide when to
stop traversing the history and mark the current commit as a shallow
root.

With this new check in place, the old check can no longer be true, since
the first check always fires first. This commit removes that check,
making the code a bit more simple again.

"git fetch --depth" was broken in at least three ways.  The
resulting history was deeper than specified by one commit, it was
unclear how to wipe the shallowness of the repository with the
command, and documentation was misleading.

* nd/fetch-depth-is-broken:
  fetch: elaborate --depth action
  upload-pack: fix off-by-one depth calculation in shallow clone
  fetch: add --unshallow for turning shallow repo into complete one

Some reimplementations of Git does not write all the stat info back
to the index due to their implementation limitations (e.g. jgit
running on Java).  A configuration option can tell Git to ignore
changes to most of the stat fields and only pay attention to mtime
and size, which these implementations can reliably update.  This
avoids excessive revalidation of contents.

* rr/minimal-stat:
  Enable minimal stat checking

When giving arguments without "--" disambiguation, object names
that come  earlier on the command line must not be interpretable as
pathspecs and pathspecs that come later on the command line must
not be interpretable as object names.  Tweak the disambiguation
rule so that ":/" (no other string before or after) is always
interpreted as a pathspec, to avoid having to say "git cmd -- :/".

gitk, when bound into the git.git project tree, used to live at the
root level, but in 62ba5143 (Move gitk to its own subdirectory,
2007-11-17) it was moved to a subdirectory.  The code used to track
changes to TCLTK_PATH (which should cause gitk to be rebuilt to
point at the new interpreter) was left in the main Makefile instead
of being moved to the new Makefile that was created for the gitk
project.

Also add .gitignore file to list build artifacts for the gitk
project.

The attribute mechanism didn't allow limiting attributes to be
applied to only a single directory itself with "path/" like the

Ramkumar Ramachandra noticed that the old address for the marc
archive no longer works.  Update it to its marc.info address,
and also refer to the gmane site.

Remove the reference to "note from the maintainer", which is not
usually followed by any useful discussion on status, direction nor
tasks.

Also replace the reference to "What's in git.git" with "What's
cooking".

Replace our use of fnmatch(3) with a more feature-rich wildmatch.
A handful patches at the bottom have been moved to nd/wildmatch to
graduate as part of that branch, before this series solidifies.

We may want to mark USE_WILDMATCH as an experimental curiosity a
bit more clearly (i.e. should not be enabled in production
environment, because it will make the behaviour between builds
unpredictable).

* nd/retire-fnmatch:
  Makefile: add USE_WILDMATCH to use wildmatch as fnmatch
  wildmatch: advance faster in <asterisk> + <literal> patterns
  wildmatch: make a special case for "*/" with FNM_PATHNAME
  test-wildmatch: add "perf" command to compare wildmatch and fnmatch
  wildmatch: support "no FNM_PATHNAME" mode
  wildmatch: make dowild() take arbitrary flags
  wildmatch: rename constants and update prototype

Since git-rev-parse already checks for the $GIT_DIR environment
variable and that it returns an actual git repository, there is no
need to repeat the checks again here.

This also fixes a problem where git-svn did not work in cases where
.git was a file with a gitdir: link.

[ew: squashed test case,
 delay setting GIT_DIR until after `git rev-parse --cdup` to fix t9101,
