bug#551: 23.0.60; C-g doesn't close minibuffer with failed tab completion

[Torsten Bronger <bronger@physik.rwth-aachen.de>]

If you want to visit a file or switch to a buffer, and you use tab completion
but it fails, a [No match] is printed in the minibuffer.  If you then press
C-g, former CVS versions of Emacs would close the minibuffer.  However now, you
have to press it twice, or wait until the [No match] is gone.
