Yes, and it could also happen with

:set fileformats=dos,unix

if you try to edit a file whose last line lacks an end-of-line. Then Vim
will treat that file as Unix-style and display the carriage returns
which are part of the Dos-style line endings (normally as ^M, but as a
hollow box, reverse-video question mark, or other placeholder if
declared "printable" by the 'isprint' setting). If this is the case,
then make sure that you have (or that your friend has) a Vim version not
earlier than 7.2.040 (the latest to date is 7.2.411) and open the file with

:e ++ff=dos filename

This way, either CR+LF ("Dos-style" EOL) or LF-only ("Unix-style" EOL)
will be seen as an end-of-line when reading, and all lines (including
the last one) will get CR+LF when writing.

Note that some other programs such as Notepad have been said to
(mistakenly) display an "empty line" after the last line when the latter
has a proper end-of-line marker.

Best regards,
Tony.
