Subject: git-gui: Use native tk_messageBox for errors.
X-Git-Tag: gitgui-0.6.0~257
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=da5239dcab0e8f899a4e6bfb34b574f6286b9dbb;p=git.git

git-gui: Use native tk_messageBox for errors.

Rather than drawing our own toplevel for error messages we really
should just use the the native tk_messageBox command to display
any error messages.

Major benefits for doing so are:
  - automatically centers over main window;
  - less code required on our part in git-gui;
  - includes a nifty error icon on most systems;
  - better fits the look-and-feel of the operating system.
