Revision 1.7, Wed May 7 21:42:50 2014 UTC (10 years ago) by zhuk
When you want more, you say "more". When you want less, you say "less". When you don't get what you asked for, you get angry. When you add a tiny bit, it should be "more" or "less" still, or you'll get angry. So lets make zmore(1) call more(1) and zless(1) call less(1), as it's supposed to be. okay and input from ingo@, no objections from author AKA millert@ |
