The two line endings returned by get_linesep_conv() are only used when
writing the files. When reading them (at least when reading them from
the workspace), monotone is trying to be smart and looks for all kinds
of line ends when it splits lines. \r, \n and \r\n are treated the
same.

For the moment, there is no 'linesep_old'. That's not how it is
defined. And really, for a text file, there's no harm at all
converting all kinds of line endings to the one that the target area
(the database or the workspace) should have. The danger is that we
don't properly recognise binary files internally, and mess them up
hugely as soon as the internal and external linesep aren't the same.
If you want to focus on something, I'd focus on getting monotone to
handle binary files in a better way (as in, at all).
Cheers,
Richard
