Yes, I did this:

because I found no way to do the diff against the first patch.
I can generate (SVN+P1)-SVN (the adjust_len patch) and
(SVN+P1+P2)-SVN (the first patch for 27663), but I cannot generate
(SVN+P1+P2)-(SVN+P1), i.e. generate a patch P2 atop of SVN+P1 without removing
So it is not possible so split a complex patch into some logical parts that
built on each other?
I removed all of P1 and attatched the proposed solution to #27663 again.

Sorry for including that in the patch. This line is very annoying and I am
removin it in my working copy
and missed to rewrite it again.
First, IMHO advising an editor should not be done from within the compiler
sources by foo-editor magic, should it?
Maybe someone else wants to tune his/her vi, jedit, Code::Blocks, TextPad,
MicroSoft-Word by avr.md ;-)
Compiler sources should not bother with the editor they may be browsed with.
Second, it's annoying because it turns on scheme mode in emacs automatically
knocks out the preferred mode in .emacs configuration. I e.g. prefer md-mode
for md-files .
Third, anyone who wants to make emacs use scheme when visiting .md can advise
emacs in his/her .emacs:
(cons '("\\.md$" . scheme-mode)
This solution will also open other md-files in scheme-mode, even without emacs
magic in every
md-file that can be found in gcc sources....
