Didn't see them here with
$ LESS= less file
on rxvt

Emacs indeed has a "(DOS)" appear in its modeline, as it is just
information, not a warning, as nothing bad is going to happen to the
file.  vi also says "[dos]".

I was being rhetorical, I think they call it.  Anyways, as the late
Ernest says, use the right tool for the right job, and for a one
character change in big file, you must agree that who's to blame me
for choosing ed instead of emacs... I had read the classics and that
is how the pros do it [when one is choosing from interactive editors,
not sed]... and what do you know, it scrambled my file while acting
like all was ok.

I had used the venerable pro stuff with no bells and whistles and my
file got scrambled like when one uses FrontPage.  Brian K. & Dennis R.
wouldn't do that... without even warning at least.
