From 3af06987eb3c376e2f1cc6dfa9c9c510b9e228cf Mon Sep 17 00:00:00 2001 From: Eric Wong Date: Sun, 29 Jan 2006 16:26:40 -0800 Subject: [PATCH] rev-list: allow -n as shorthand for --max-count= Both -n and -n are supported. POSIX versions of head(1) and tail(1) allow their line limits to be parsed this way. I find --max-count to be a commonly used option, and also similar in spirit to head/tail, so I decided to make life easier on my worn out (and lazy :) fingers with this patch.
