Oh boy... this is a big one! This is patch #5 to Pcomm v1.1.
This patch will fix:
1) a zillion places where NULL should have been '\0'.
2) two places where it was possible to deference a NULL pointer.
3) the selection-of-the-TTY bug when the index field is used.
4) the bug on shell escape that allowed suspend() to get confused.
WARNING: The very first patch is to change the mistake I made in the
Doc file patch in Patch #4. Many people have already made that change
by hand... if so, be very careful with the first message from patch about
"patch already applied, assume reversed?"
