   I don't believe I put it in when I wrote the '-A' code.  (Which, FWIW, was
   originally written and tested on BSD/OS, in response to accidentally restoring
   an old tar file *over* my home directory, instead of in a sandbox.)


i have commited a change to options.h (rev1.5) that should fix this bug
(which would allow -A with -rw; reading the code shows that it *always*
does the equivalent of -A anyway).
