+By default, Thunderbird will both wrap emails as well as flag them as

 Here are some hints on how to successfully submit patches inline using
 Thunderbird.
 
+There are two different approaches.  One approach is to configure

+This recipe is current as of Thunderbird 2.0.0.19.  Three steps:
+  1.  Configure your mail server composition as plain text

+      toggle it to make sure it is set to 'false'.

+Checklist for Shrinking a Repository
+------------------------------------
+
+git-filter-branch is often used to get rid of a subset of files,
+usually with some combination of `\--index-filter` and
+`\--subdirectory-filter`.  People expect the resulting repository to
+be smaller than the original, but you need a few more steps to
+actually make it smaller, because git tries hard not to lose your
+objects until you tell it to.  First make sure that:
+
+* You really removed all variants of a filename, if a blob was moved
+  over its lifetime.  `git log \--name-only \--follow \--all \--
+  filename` can help you find renames.
+
+* You really filtered all refs: use `\--tag-name-filter cat \--
+  \--all` when calling git-filter-branch.
+
+Then there are two ways to get a smaller repository.  A safer way is
+to clone, that keeps your original intact.
+
+* Clone it with `git clone +++file:///path/to/repo+++`.  The clone
+  will not have the removed objects.  See linkgit:git-clone[1].  (Note
+  that cloning with a plain path just hardlinks everything!)
+
+If you really don't want to clone it, for whatever reasons, check the
+following points instead (in this order).  This is a very destructive
+approach, so *make a backup* or go back to cloning it.  You have been
+warned.
+
+* Remove the original refs backed up by git-filter-branch: say `git
+  for-each-ref \--format="%(refname)" refs/original/ | xargs -n 1 git
+  update-ref -d`.
+
+* Expire all reflogs with `git reflog expire \--expire=now \--all`.
+
+* Garbage collect all unreferenced objects with `git gc \--prune=now`
+  (or if your git-gc is not new enough to support arguments to
+  `\--prune`, use `git repack -ad; git prune` instead).

+This directory contains various modules for Emacs support.
+
+To make the modules available to Emacs, you should add this directory
+to your load-path, and then require the modules you want. This can be
+done by adding to your .emacs something like this:
+
+  (add-to-list 'load-path ".../git/contrib/emacs")
+  (require 'git)
+  (require 'git-blame)
+
+
+The following modules are available:
+
+* git.el:
+
+  Status manager that displays the state of all the files of the
+  project, and provides easy access to the most frequently used git
+  commands. The user interface is as far as possible compatible with
+  the pcl-cvs mode. It can be started with `M-x git-status'.
+
+* git-blame.el:
+
+  Emacs implementation of incremental git-blame.  When you turn it on
+  while viewing a file, the editor buffer will be updated by setting
+  the background of individual lines to a color that reflects which
+  commit it comes from.  And when you move around the buffer, a
+  one-line summary will be shown in the echo area.
+
+* vc-git.el:
+
+  This file used to contain the VC-mode backend for git, but it is no
+  longer distributed with git. It is now maintained as part of Emacs
+  and included in standard Emacs distributions starting from version
+  22.2.
+
+  If you have an earlier Emacs version, upgrading to Emacs 22 is
+  recommended, since the VC mode in older Emacs is not generic enough
+  to be able to support git in a reasonable manner, and no attempt has
+  been made to backport vc-git.el.
