Two more uucp bugs
Two bugs I recently found in uucp.  There are up to six possible fields
that can be specified in the command file (the C. file).  For R (receive)
and X (remote uucp) commands, though, not all of the fields are set.
Unfortunately, some of the code assumes these fields are set.  What you
are left with are stray pointers that can cause a core dump.

Here are the fixes:
