IMHO, in Vim 7.2.040 and later, by opening it with
:e ++ff=dos somestuff.txt
This will force Vim to read it as if it were a DOS file, which in turn
means that CR (carriage return, or ^M) characters will be ignored
whenever they are immediately followed by a LF (linefeed), and that LF
will be accepted as an end-of-line marker regardless of whether it is
preceded by a CR.
Then if you want to write it with LF-only ("Unix-style") ends of lines,
so that no Unix program "sees" the carriage returns, use
:setlocal ff=unix
once the file is open, and before saving it; otherwise Vim will write
the file with CR+LF ("DOS-style") ends of lines throughout, and the next
time it reads the file, it will regard it as a "dos" file and you won't
see the ^M characters.
(Before 7.2.040, files with mixed CR+LF and LF-only ends-of-lines would
be opened as fileformat "unix" even if you used the ++ff=dos modifier,
unless 'fileformats' (plural) was set to empty or just "dos".)
Trailing ^M characters mean that the file has mixed ends-of-lines
(assuming that 'fileformats' [plural] contains both "unix" and "dos").
Often, such a file actually has CR+LF throughout, except on the last
line which has nothing at all.
Best regards,
Tony.
