From 88d3406ad77dbab4d8ea76756822531228332b1b Mon Sep 17 00:00:00 2001 From: David Aguilar Date: Fri, 25 Jan 2013 01:43:54 -0800 Subject: [PATCH] mergetool--lib: improve show_tool_help() output Check the can_diff and can_merge functions before deciding whether to add the tool to the available/unavailable lists. This makes "--tool-help" context-sensitive so that "git mergetool --tool-help" displays merge tools only and "git difftool --tool-help" displays diff tools only.
