rsync 2.6.4 - directory always updated

[John Stoffel]

Well, after some more checking and re-checking, it turns out that I
had the 'nosuid' option set on the exportfs file on the destination
filer.  When you do a 'chmod g+s' on a directory, it succeeds, but the
filer just squashes the bit.

So rsync was working fine, but not catching an error which would be
hard to catch and which would put alot of overhead into the system if
it had to do another loop to check permissions after each 'chmod'
call, though it could do so if the 'sticky' bit was set for sanities
sake.

Thanks,
John
