Hmm, I can't imagine that people doing a clean checkout would expect
to find modified files, much less have to commit changes. And what
happens if they *don't* commit, but hack and then commit. If 2 people
do that, you'll have a merge to do, which will be mangled by EOL
conflicts (I suspect - not tried this to be sure).

Sounds like there are a number of edge cases that need thinking through here :-)

Not sure that'd work as people expect either. If I change .hgeol, then
commit and *other* files get committed, I think I'd be surprised (even
if I understood why it happened after reading the docs...)
