It was done on 2004-03-25 to fix some other problem with Windows paths
that had been discussed on the list around that time.
The general philosophy is that Windows paths should be left alone (no mount
table processing).
By the way, the User's guide still states that the default is "text".
It has been "binary" for the last couple of years.

It relies on the application asking for a binary/text open in open() or
fopen(), or being linked with binmode.o or one of its friends.
The mount modes are only used as a last recourse, just before taking the
default (see fhandler_base::set_flags).
