From 8233340ce6eb700eb2cd9c0fef4d1705997c499b Mon Sep 17 00:00:00 2001 From: Eric Wong Date: Sun, 29 Jan 2006 16:28:02 -0800 Subject: [PATCH] rev-list: allow - as shorthand for --max-count= This builds on top of the previous one. Traditionally, head(1) and tail(1) allow their line limits to be parsed this way.
