CVS commit: othersrc/usr.bin/grep

[Chris Pinnock <cjep%netbsd.org@localhost>]

Module Name:    othersrc
Committed By:   cjep
Date:           Sun Apr  6 11:26:19 UTC 2003

Modified Files:
        othersrc/usr.bin/grep: grep.c grep.h util.c

Log Message:
1. Make the default behaviour to warn about directory cycles. e.g.
where test/foo/foo -> test/foo:

./grep -rl chris test
test/foo/chris
grep: warning: test/foo/foo: recursive directory loop

2. Replace code dealing with -P, -S and the former -H option with
   code to handle a long option called --links. Comment this out (it
   still needs some work). Temporarily remove -P, -S.
