Log Message:
   Support gnu long filename extensions by default for tar on create, list, and
   extract. We now generate GNU tar archives by default ("ustar  ^@" instead of
   "ustar^@00"). GNU extensions can be disabled with --strict.

do we have to do this?  can't we please only use it when necessary?
   
   XXX: long symlinks untested.

these used to work a few years ago.
