Serious Bug in rdiff-backup

[Robert.Weber@Colorado.EDU]

Rdiffbackup, when the --change-source-perms breaks high mode permissions.
(sticky, suid, sgid) bits.  The problem is bad on suns where

> ls -l /usr/lib/pt_chmod 
---s--x--x    1 root     bin          4104 Jan  5  2000 /usr/lib/pt_chmod*

after a backup

> ls -l /usr/lib/pt_chmod 
---x--x--x    1 root     bin          4104 Jan  5  2000 /usr/lib/pt_chmod*

this prevents anyone from logging into the console.  :(  I am unfamiliar
with this part of the code, if anyone out there knows how to get this fixed
cleanly, go for it, if not I'll try to get the patch myself.
