-3RD PARTY BUGS:
-
- * redhat (v?) graphical install bomb-out?
-
- * GNU diff 2.7: diff -rN does not see a new directory with empty file
-
- * GNU patch 2.1: <must find simple example> if patch chokes on a
- hunk, or on allegedly unsorted hunks in a diff, it may stop
- without a trace of failure (create .rej file, print error or
- dump core) and just ignore any further diffs.
