-;; The actual article treatment code
-(defun ft/gnus-article-treat-patch-state-machine ()
-  "Implement the state machine which colourises a part of an article
-if it looks patch-like.
-
-The state machine works like this:
-
-  0a. The machinery starts at the first line of the article's body. Not
-      the header lines. We don't care about header lines at all.
-
-  0b. The whole thing works line by line. It doesn't do any forward or
-      backward looks.
-
-  1. Initially, we assume, that what we'll see first is part of the
-     patch's commit-message. Hence this first initial state is
-     \"commit-message\". There are several ways out of this state:
-
-       a) a scissors line is found (see 2.)
-       b) a pseudo-header line is found (see 3.)
-       c) a three-dashes line is found (see 4.)
-       d) something that looks like the start of a unified diff is
-          found (see 7.)
-
-  2. A scissors line is something that looks like a pair of scissors running
-     through a piece of paper. Like this:
-
-      ------ 8< ----- 8< ------
-
-     or this:
-
-      ------------>8-----------
-
-     The function `ft/gnus-scissors-line-p' decides whether a line is a
-     scissors line or not. After a scissors line was treated, the machine
-     will switch back to the \"commit-mesage\" state.
-
-  3. This is very similar to a scissors line. It'll just return to the old
-     state after its being done. The `ft/gnus-pseudo-header-p' function
-     decides if a line is a pseudo header. The line will be appropriately
-     coloured.
-
-  4. A three-dashes line is a line that looks like this: \"---\". It's the
-     definite end of the \"commit-message\" state. The three dashes line is
-     coloured and the state switches to \"commit-comment\". (See 5.)
-
-  5. Nothing in \"commit-comment\" will appear in the generated commit (this
-     is git-am specific semantics, but it's useful, so...). It may contain
-     things like random comments or - promimently - a diff stat. (See 6.)
-
-  6. A diff stat provides statistics about how much changed in a given commit
-     by files and by whole commit (in a summary line). Two functions
-     `ft/gnus-diff-stat-line-p' and `ft/gnus-diff-stat-summary-p' decide if a
-     line belongs to a diff stat. It's coloured appropriately and the state
-     switches back to \"commit-comment\".
-
-  7. There is a function `ft/gnus-unified-diff-line-p' which will cause the
-     state to switch to \"unified-diff\" state from either \"commit-message\"
-     or \"commit-comment\". In this mode there can be a set of lines types:
-
-       a) diff-header lines (`ft/gnus-diff-header-p')
-       b) index lines (`ft/gnus-index-line-p')
-       c) hunk lines (`ft/gnus-hunk-line-p')
-       d) equals line (\"^==*$\")
-       e) context lines (\"^ \")
-       f) add lines (\"^\\+\")
-       g) remove lines (\"^-\")
-       h) empty lines (\"^$\")
-
-     This state runs until the end of the part."

-(defun ft/gnus-article-treat-patch ()
-  "Highlight mail parts, that look like patches (well, usually
-they *are* patches - or possibly, when you take git's format-patch output,
-entire commit exports - including comments).  This treatment assumes the
-use of unified diffs.  Here is how it works:
-
-The most fancy type of patch mails look like this:
-
-  From: ...
-  Subject: ...
-  Other-Headers: ...
-
-  Body text, which can be reflecting the commit message but may
-  optionally be followed by a so called scissors line, which
-  looks like this (in case of a scissors line, the text above is
-  not part of the commit message):
-
-  -------8<----------
-
-  If there really was a scissors line, then it's usually
-  followed by repeated mail-headers. Which do not *have* to
-  be the same as the one from the sender.
-
-  From: ...
-  Subject: ...
-
-  More text. Usually part of the commit message. Likely
-  multiline.  What follows may be an optional diffstat. If
-  there is one, it's usually preceded by a line that contains
-  only three dashes and nothing more. Before the diffstat,
-  however, there may be a set of pseudo headers again, like
-  these:
-
-  Acked-by: Mike Dev <md@other.tld>
-  Signed-off-by: Joe D. User <jdu@example.com>

-  ChangeLog                    |    5 ++++-
-  1 file changed, 4 insertions(+), 1 deletions(-)
-
-  Now, there is again room for optional text, which is not
-  part of the actual commit message. May be multiline. Actually,
-  anything between the three-dashes line and the diff content
-  is ignored as far as the commit message goes.
-
-  Now for the actual diff part.  I want this to work for as
-  many unified diff formats as possible.  What comes to mind
-  is the format used by git and the format used by cvs and
-  quilt.

-  CVS style looks like this:

-  There may be multiple hunks. Each file gets an \"Index:\" and
-  equals line.  Now the git format looks like this:

-  Again, there may be multiple hunks.

-  When all hunks and all files are done, there may be additional

-
-And that's it.
-
-You may define the look of several things: pseudo headers, scissor
-lines, three-dashes-line, equals lines, diffstat lines, diffstat
-summary. Then there is added lines, removed lines, context lines,
-diff-header lines and diff-file-header lines, for which we are
-borrowing the highlighting faces for from `diff-mode'."
