as suggested by Thomas de Grivel <billitch at gmail dot com> on tech@.
While here, remove the SEE ALSO entries (but not the cross references
at the appropriate places!) to fnmatch(3), re_format(7), and pr(1).
Their relevance is restricted to one single option each, the latter
is mostly obsolete nowadays anyway, and the number of SEE ALSO entries
is so large that SEE ALSO is starting to look confusing.

FIFOs shall be skipped. Other types of files may be skipped too
(this is implementation-dependent). In directory mode, just skip
anything that is not a regular file or directory. OK tedu@

- note (again) that output options are mutually exclusive

- remove "mutually exclusive" clause
- -c produces 15 *'s, not a dozen
- add -a to uage()
- sync usage() with SYNOPSIS

producing suboptimal diffs for large file containing lots of changes.
Switch heuristic off with -d/--minimal (GNU compatible). Some hints
from millert@.
- Improve performance by reducing the number of realloc(3) calls.

o -N is implemented
o -X is implemented
o -x is implemented
o diff.c has been rewritten and GNU long options are now supported
o diffdir.c has been rewritten
+ no longer does fork + exec of /usr/bin/diff
+ can be called recursively (and will be for -r)
o diff.h
+ don't include any .h files here any more, do it in the .c files
+ no Bell Labs code in this, gets a UCB copyright (the 32v sources
only have a diff.c and there is nothing in common).
o diffreg.c
+ most all remaining globals are now private to diffreg.c
+ files are only opened once
+ dynamically allocated objects are either freed or realloced
+ added missing UCB copyright (there were lots of UCB changes)
+ print correct thing when -s is specified
