[PATCH] Documentation/email-clients.txt: clarify Thunderbird section

[Alan Jenkins <alan-jenkins@tuffmail.co.uk>]

1) Make it clearer that there are three different methods here,
   by using two different levels of indentation.

2) Reorder the different methods:

  - Disabling word wrap altogether should be the last option.
    It involves manually editing config files, and many Thunderbird
    users will not want to disable word wrap for normal (non-patch)
    messages.

  - "Preformat mode" should be the first option. It's really convenient.
    (Guess how I sent this patch).

 Thunderbird (GUI)
 
 By default, thunderbird likes to mangle text, but there are ways to
-coerce it into being nice.
-
-- Under account settings, composition and addressing, uncheck "Compose
-  messages in HTML format".
-
-- Edit your Thunderbird config settings to tell it not to wrap lines:
-      user_pref("mailnews.wraplength", 0);
-
-- Edit your Thunderbird config settings so that it won't use format=flowed:
-      user_pref("mailnews.send_plaintext_flowed", false);
-
-- You need to get Thunderbird into preformat mode:
-. If you compose HTML messages by default, it's not too hard. Just select
-  "Preformat" from the drop-down box just under the subject line.
-. If you compose in text by default, you have to tell it to compose a new
-  message in HTML (just as a one-off), and then force it from there back to
-  text, else it will wrap lines. To do this, use shift-click on the Write
-  icon to compose to get HTML compose mode, then select "Preformat" from
-  the drop-down box just under the subject line.
-
-- Allows use of an external editor:
-  The easiest thing to do with Thunderbird and patches is to use an
-  "external editor" extension and then just use your favorite $EDITOR
-  for reading/merging patches into the body text.  To do this, download
-  and install the extension, then add a button for it using
