I would love to see "diff=tex" attribute to work on my manuscripts, but I
do not write C and do not understand the long length of backslashes very
well.  I guessed in the source file a backslash needs to be doubled, and
what I want to match is "\section{", "\subsection{", and "\subsubsection{"
at the beginning of lines, and attempted to do it like the patch at the
end.

It does not work well, however.  It shows only part of lines.

	@@ -224,7 +225,7 @@ sub
	@@ -240,7 +241,7 @@ subsub

I have no idea what am I doing wrong (truthfully, I do not know what I am
doing, period).
