 Some of patches I receive or pick up from the list share common
 patterns of breakage.  Please make sure your MUA is set up
-properly not to corrupt whitespaces.  Here are two common ones
-I have seen:
+properly not to corrupt whitespaces.
 
-* Empty context lines that do not have _any_ whitespace.
+See the DISCUSSION section of git-format-patch(1) for hints on
+checking your patch by mailing it to yourself and applying with
+git-am(1).
 
-* Non empty context lines that have one extra whitespace at the
-  beginning.
-
-One test you could do yourself if your MUA is set up correctly is:
-
-* Send the patch to yourself, exactly the way you would, except
-  To: and Cc: lines, which would not contain the list and
-  maintainer address.
-
-* Save that patch to a file in UNIX mailbox format.  Call it say
-  a.patch.
-
-* Try to apply to the tip of the "master" branch from the
-  git.git public repository:
-
-    $ git fetch http://kernel.org/pub/scm/git/git.git master:test-apply
-    $ git checkout test-apply
-    $ git reset --hard
-    $ git am a.patch
-
-If it does not apply correctly, there can be various reasons.
-
-* Your patch itself does not apply cleanly.  That is _bad_ but
-  does not have much to do with your MUA.  Please rebase the
-  patch appropriately.
-
-* Your MUA corrupted your patch; "am" would complain that
-  the patch does not apply.  Look at .git/rebase-apply/ subdirectory and
-  see what 'patch' file contains and check for the common
-  corruption patterns mentioned above.
-
-* While you are at it, check what are in 'info' and
-  'final-commit' files as well.  If what is in 'final-commit' is
-  not exactly what you would want to see in the commit log
-  message, it is very likely that your maintainer would end up
-  hand editing the log message when he applies your patch.
-  Things like "Hi, this is my first patch.\n", if you really
-  want to put in the patch e-mail, should come after the
-  three-dash line that signals the end of the commit message.
+While you are at it, check the resulting commit log message from

-
-By default, Thunderbird will both wrap emails as well as flag them as
-being 'format=flowed', both of which will make the resulting email unusable
-by git.
-
-Here are some hints on how to successfully submit patches inline using
-Thunderbird.
-
-There are two different approaches.  One approach is to configure
-Thunderbird to not mangle patches.  The second approach is to use
-an external editor to keep Thunderbird from mangling the patches.
-
-Approach #1 (configuration):
-
-This recipe is current as of Thunderbird 2.0.0.19.  Three steps:
-  1.  Configure your mail server composition as plain text
-      Edit...Account Settings...Composition & Addressing,
-        uncheck 'Compose Messages in HTML'.
-  2.  Configure your general composition window to not wrap
-      Edit..Preferences..Composition, wrap plain text messages at 0
-  3.  Disable the use of format=flowed
-      Edit..Preferences..Advanced..Config Editor.  Search for:
-        mailnews.send_plaintext_flowed
-      toggle it to make sure it is set to 'false'.
-
-After that is done, you should be able to compose email as you
-otherwise would (cut + paste, git-format-patch | git-imap-send, etc),
-and the patches should not be mangled.
-
-Approach #2 (external editor):
-
-This recipe appears to work with the current [*1*] Thunderbird from Suse.
-
-The following Thunderbird extensions are needed:
-	AboutConfig 0.5
-		http://aboutconfig.mozdev.org/
-	External Editor 0.7.2
-		http://globs.org/articles.php?lng=en&pg=8
-
-1) Prepare the patch as a text file using your method of choice.
-
-2) Before opening a compose window, use Edit->Account Settings to
-uncheck the "Compose messages in HTML format" setting in the
-"Composition & Addressing" panel of the account to be used to send the
-patch. [*2*]
-
-3) In the main Thunderbird window, _before_ you open the compose window
-for the patch, use Tools->about:config to set the following to the
-indicated values:
-	mailnews.send_plaintext_flowed	=> false
-	mailnews.wraplength		=> 0
-
-4) Open a compose window and click the external editor icon.
-
-5) In the external editor window, read in the patch file and exit the
-editor normally.
-
-6) Back in the compose window: Add whatever other text you wish to the
-message, complete the addressing and subject fields, and press send.
-
-7) Optionally, undo the about:config/account settings changes made in
-steps 2 & 3.

-KMail
------
-
-This should help you to submit patches inline using KMail.
-
-1) Prepare the patch as a text file.
-
-2) Click on New Mail.
-
-3) Go under "Options" in the Composer window and be sure that
-"Word wrap" is not set.

-Gmail
------
-
-GMail does not appear to have any way to turn off line wrapping in the web
-interface, so this will mangle any emails that you send.  You can however
-use "git send-email" and send your patches through the GMail SMTP server, or
-use any IMAP email client to connect to the google IMAP server and forward
-the emails through that.
-
-To use "git send-email" and send your patches through the GMail SMTP server,
-edit ~/.gitconfig to specify your account settings:
-
-[sendemail]
-	smtpencryption = tls
-	smtpserver = smtp.gmail.com
-	smtpuser = [email protected]
-	smtppass = p4ssw0rd
-	smtpserverport = 587
-
-Once your commits are ready to be sent to the mailing list, run the
-following commands:
-
-  $ git format-patch --cover-letter -M origin/master -o outgoing/
-  $ edit outgoing/0000-*
-  $ git send-email outgoing/*
-
-To submit using the IMAP interface, first, edit your ~/.gitconfig to specify your
-account settings:
-
-[imap]
-	folder = "[Gmail]/Drafts"
-	host = imaps://imap.gmail.com
-	user = [email protected]
-	pass = p4ssw0rd
-	port = 993
-	sslverify = false
-
-You might need to instead use: folder = "[Google Mail]/Drafts" if you get an error
-that the "Folder doesn't exist".
-
-Once your commits are ready to be sent to the mailing list, run the
-following commands:
-
-  $ git format-patch --cover-letter -M --stdout origin/master | git imap-send
-
-Just make sure to disable line wrapping in the email client (GMail web
-interface will line wrap no matter what, so you need to use a real
-IMAP client).
