option to mask entered command

[landroni]

Would you consider to add an option to NOT display the entered command? I use gmrun with history disabled (History = 0), to run sensitive commands. And I would like to have an option where gmrun treats the command that I input as a "password", in the sense that it doesn't display it on screen. Would it be difficult to add that?

And I was wondering if you were planning to make a release? Or will this repo stay as a fork? Thanks!
