But pressing Shift on booting shows "GRUB loading." so there is
somewhere a successfull check for Shift performed. I think grub should
either never show "GRUB loading." if it wouldn't result in loading the
menu or on a timeout of 0 pressing Shift should have a higher priority

Bug description:
  I'm using Ubuntu 15.04 dev with grub-pc 2.02~beta2-18 and this bug was
  already reported on upstream but they requested to report it to the
  related distribution: http://savannah.gnu.org/bugs/?40853


  It is not possible to configure GRUB anymore to automatically boot
  instantly to the default operating system in a multi-system
  environment while having the ability to show the GRUB menu if the
  related button (shift on my system) is keeping pressed while booting.

  In comment #2 of the upstream report is an example configuration how
  to reproduce this behavior. Keeping shift pressed while booting does
  then show "GRUB loading." but the GRUB menu will not appear. Instead
  GRUB will immediately boot to the default operating system.
