No. It's about files that must, when checked out on Windows, have CRLF
endings, and, when checked out on Unix, have LF endings - i.e. all the
.py, .c, .h, and .rst files, plus a couple of others which don't require

In addition, a DVCS brings in another problem dimension: when people
push their changes, they have *already* committed them - and perhaps not
even they, but a contributor from which they had been pulling changes.
The bogus change may have been weeks ago, so the subversion solution
(of rejecting the commit to happen) doesn't quite work that well for
