bug#24339: 24.5; Need double c-g to quit from a minibuffer

[Yujie Zhou <zhou@lorentz.leidenuniv.nl>]

Dear Emacs maintainers,

on this device I need double pressing C-g to quit from a minibuffer, 
even starting from 'emacs -Q'. More specifically, after pressing C-x 
C-f, if I do not realease the control botton, I only need one C-g to 
quit the minibuffer. But if I realease, I need two. If I only press C-g 
once, the minibuffer shows the text quit, but the cursor is still 
focused on the minibufer, and I have to press C-g again within 3 
seconds, otherwise the Find-File minibuffer reappears after the text 
quit fades in 3 seconds. And in that case, I need to double-press again 
to quit.
