Thanks for the story!  Since 65535 does not reflect a real
limit, I've changed this paragraph to

     `tar-pax' selects the new pax interchange format defined by POSIX
     1003.1-2001.  It does not limit the length of filenames.  However,
     this format is very young and should probably be restricted to
     packages which target only very modern platforms.  There are moves
     to change the pax format in an upward-compatible way, so this
     option may refer to a more recent version in the future.
