Interesting.  When I get a copy of a DOS format text file (in native format)
and look at it with vi, each line has a "^M" at its end.  My file command
reports this file as a DOS format text file.  If I take a UNIX text file
into vi and do a global substitute:

	%s/$/^-V<CR>/    #  what I see: %s/$/^M/

I get ^M displayed at the end of each line.  Saving this and then running
the file command on it tells me I have a DOS format text file, ie one
with carriage return/linefeed at the end of each line.

If the input ^M were made into a linefeed the file should still be UNIX
only double spaced (in this example).  So under XENIX 2.[23].x and AT&T
UNIX SysV/386 Rel 3.2 there is no conversion of cr to nl set by vi.
Other systems may do this and I would be interested in knowing which ones.
