Not sure it has anything to do with re.match. Most likely it's caused
by the line that appends ':\n'. This is probably written to file
as '\r\n' (CR/LF) (in Windows). I suspect that some other lines
only have '\n' (LF) as a line separator, otherwise gvim would not show
them; it usually detects the line ending and displays the text
accordingly.
The solution is to make sure that your lines have either a Windows
or a Unix line ending, but not a mix. Use os.linesep when in doubt.
