This commit is what this branch is all about. It records the
evil merge needed to adjust built-in git-add and git-rm for
the cache-tree extension.
* lt/dirwalk:
Add builtin "git rm" command
Move pathspec matching from builtin-add.c into dir.c
Prevent bogus paths from being added to the index.
builtin-add: fix unmatched pathspec warnings.
Remove old "git-add.sh" remnants
builtin-add: warn on unmatched pathspecs
Do "git add" as a builtin
Clean up git-ls-file directory walking library interface
libify git-ls-files directory traversal

+================

+NAME
+----
+git-quiltimport - Applies a quilt patchset onto the current branch
+
+
+SYNOPSIS
+--------
+[verse]
+'git-quiltimport' [--dry-run] [--author <author>] [--patches <dir>]
+
+
+DESCRIPTION
+-----------
+Applies a quilt patchset onto the current git branch, preserving
+the patch boundaries, patch order, and patch descriptions present
+in the quilt patchset.
+
+For each patch the code attempts to extract the author from the
+patch description. If that fails it falls back to the author
+specified with --author. If the --author flag was not given
+the patch description is displayed and the user is asked to
+interactively enter the author of the patch.
+
+If a subject is not found in the patch description the patch name is
+preserved as the 1 line subject in the git description.
+
+OPTIONS
+-------
+--dry-run::
+ Walk through the patches in the series and warn
+ if we cannot find all of the necessary information to commit
+ a patch. At the time of this writing only missing author
+ information is warned about.
+
+--author Author Name <Author Email>::
+ The author name and email address to use when no author
+ information can be found in the patch description.
+
+--patches <dir>::
+ The directory to find the quilt patches and the
+ quilt series file.
+
+ The default for the patch directory is patches
+ or the value of the $QUILT_PATCHES environment
+ variable.
