Um, we have to consider 8.3 shortname mappings?

It might make sense to draw a line somewhere and at least
assume something minimally sensible like the long file name capabilities
of a FAT32 as a minimum standard when considering _working dir_ folding
issues (isn't FAT16 limited to 2GB volumes anyway? and who still buys
< 2GB sticks these days?).

IMHO, the importance of the folding properties of working dirs on thumbdrives
is somewhat questionable anyway, since the interesting bits of repositories
on removable flash memory are normally inside the .hg directory for
relevant use cases.
