[PATCH 2/2] git-gui: add hotkey to toggle "Amend Last Commit" check button/menu

[Bert Wesarg <bert.wesarg@googlemail.com>]

From: Birger Skogeng Pedersen <birger.sp@gmail.com>

Selecting whether to "Amend Last Commit" or not does not have a hotkey.

With this patch, the user may toggle between the two options with
CTRL/CMD+e.
