Makes sense.

Not all Windows editors will handle Unix line endings (LE). The 
editor that I ship with WinAVR, Programmers Notepad 2, does handle it 
and support for it is improving.

The other issue has to do with debugging. I remember seeing posts 
(and I think Volkmar has been the one responding to these) I think it 
was about the source in the debugging was all on 1 line? Which I 
believe was due to Unix LE in the source.

I'm not proposing to poison the files with CRs. That's why I 
mentioned converting them off-line before I ship.

I would be converting all example source files, .c, .h, makefile. 
Anything that can, would, and should be edited by a user. Because I 
can't guarantee that a user's editor can handle Unix LEs.
