This will delete carriage -returns anywhere in the file, but only the
first one if there are several on a line. You may prefer
:%s/\r$//
to remove only carriage-returns at end-of-line. (Some programs such as
rsync use carriage-returns without line-feed on sysout to erase the
current line without going to the next line; these "naked CRs" are
visible when redirecting the program's output to a logfile.)

You may also force-read with one specific type of line endings, but it
will only work if 'fileformats' (plural) is empty: see ":help ++opt".
The "dos" fileformat will then treat _either_ CR+LF or LF alone as and
end-of-line when reading, and will write CR+LF when writing.
For instance
command -bang -bar -nargs=? -complete=file EditAsDos
\ call EditAsDos(<q-args>,<q-bang>)
function EditAsDos(file,bang)
let save_ffs = &ffs
set ffs=
exe "edit" . a:bang "++ff=dos" a:file
let &ffs = save_ffs
endfunction
Best regards,
Tony.
