ports-rsync.patch prevents rsync from backing up FIFO files

[CsMAr51]

Since the patch for rsync has been added, it can't handle FIFO type files anymore. When it encounter this type of file, it hangs indefinitely. In my case the files are "pickup" and "qmgr":

[root@pe2850 ~]# ls -lA /var/spool/postfix/public/
total 0
srw-rw-rw-  1 postfix  maildrop  0 Nov 22 07:52 cleanup
srw-rw-rw-  1 postfix  maildrop  0 Nov 22 07:52 flush
prw--w--w-  1 postfix  maildrop  0 Nov 22 07:52 pickup
prw--w--w-  1 postfix  maildrop  0 Nov 22 07:52 qmgr
srw-rw-rw-  1 postfix  maildrop  0 Nov 22 07:52 showq

The same effect can be reproduced with any FIFO file (mkfifo <filename>).

I'm doing an rsync from a FreeBSD 8.2-STABLE-amd64 to FreeNAS-8.2-r8945M-amd64/FreeNAS-8.0.3-BETA2-amd64 (9071):

• FreeNAS-8.0.3-BETA2-amd64: rsync hangs on FIFO file
• FreeNAS-8.2-r8945M-amd64: rsync hangs on FIFO file
• FreeNAS-8.2-r8945M-amd64 (without ports-rsync.patch): rsync works as expected
