[PATCH 4/7] minibar: show the info bar again some 0.8 seconds after a message

[Benno Schulenberg]

Instead of redisplaying the minibar only upon the next keystroke
(when some feedback message is shown on the status bar), time the
waiting for the keystroke out after four fifths of a second, then
redisplay the minibar and continue the wait.
