Subject: [PATCH] more meaningful error message in gitk when git binary is not available
Date: Mon, 01 Oct 2012 09:17:20 +0200	[thread overview]
Message-ID: <50694380.4090108@josefassad.com> (raw)

Hi. I ran across what is a decidedly trivial little issue in gitk. The
TCL/Tk looked simple enough so I am giving you a patch anyhow in case
you want to fix it.

When for whatever reason the git binary is unavailable, gitk would
complain about missing git repository instead, so this patch adds a
check for git binary availability.

In case anyone is curious, I found this issue here:
