From f47f1e2ce8b4022113120b32decb4436341dc3aa Mon Sep 17 00:00:00 2001 From: David Aguilar Date: Fri, 15 Jan 2010 14:03:43 -0800 Subject: difftool: Add '-x' and as an alias for '--extcmd' This adds '-x' as a shorthand for the '--extcmd' option. Arguments to '--extcmd' can be specified separately, which was not originally possible. This also fixes the brief help text so that it mentions both '-x' and '--extcmd'.
