	Subject: Handle '/' in filenames in broken ISO9660 images

[Also applicable to 2.2.x]

There has been for some time a problem with certain CD-ROMs whose images
were generated using a particular tool on Acorn RISC OS.  The problem is
that in certain catalogue entries, the extension separator character '/'
(RISC OS uses '.' and '/' the other way round) was not replaced with '.';
thus Linux cannot properly parse this without this patch, thinking that it
is a directory separator.
