What steps will reproduce the problem?

1. Right click on a commit in Log Messages dialog
2. do Show branches this commit is on
3. TGit shows the result in Git Command Progress dialog

What is the expected output? What do you see instead?

Expected 1:
Shows the listed branch(es) in Log Messages dialog when push the Close button in Git Command Progress dialog

or Expected 2:
There is a button named "Show branch(es)" in Git Command Progress dialog.
When push "Show branch(es)" button, close the Git Command Progress dialog and shows the listed branch(es) automatically in Log Messages dialog.

Instead:
Only lists the branch(es) name in Git Command Progress dialog.

What version of TortoiseGit and msysgit are you using? On
what operating system?
TGit 1.8.6.4
msysGit 1.8.4
Win7 64

Please provide any additional information below.

1. Inspired by Issue #2012 (closed).

2. The wiki page for the idea:
   https://code.google.com/p/tgit-wiki-ylh/wiki/zi2012?ts=1386135867&updated=zi2012

3. Perhaps "Show branches this commit is on" should be "List branches this commit is on". :)
