Give last split-floppy for each X11 set, for 1.3.
FIXME: if the number of floppies in any split set changes for 1.3.1,
syinst is hosed for 1.3.1. Same is true for any release: we can't
install from split sets if the count of floppies doesn't match
the precompiled version.
The number of floppies in a split set should be computed dynamically
from a directory listing, or read from a config file in the split
directory.
