I would hope that using ";" as path separator in the PATH directive 
would not be a problem for ISO9660 fs and ISOLINUX, where the ";" is 
used in the standard specification to indicate the 'Version Number' 
of files (";1"). In practice, this Version Number is not always used, 
yet it is still part of the standard.

Additionally, ";" is still a valid character for directory names in 
several fs.

My apologies if this is not at all a concern and thus not relevant. 
I'd rather just mention it now in case it happens to be relevant, 
than to see a new potential conflict with a new possible 
path-separator.

Best Regards,
Ady.
