One reason was not to confuse human readers, who get a message containing
the file path.
It seemed strange that Mozilla 1.7.3 fails whereas Firefox succeeds (and
even IE6 succeeds). So I installed Mozilla to find out, and it does work
for me (Windows XP SP2). So it's something to do with your system vs
mine, not different browsers.
I think I need to do some more extensive tests to decide if the right fix
is to use a filespec with \ or a file:// URL. One problem about the
latter is that some browser used to require : replaced by | -- I think it
was Netscape4 but I don't know if it is relevant.
