Subject: git-gui: Make usage statement visible on Windows.
X-Git-Tag: gitgui-0.13.0~7
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/ea47503d4dc80db54dbb8e568f7a7058ec25bacb

git-gui: Make usage statement visible on Windows.

On Windows stdout and stderr are not connected to anything so the usage
statement is never shown to the user when an error is made with a command
line like 'git gui browser'. Use a messagebox on windows.
