Dired not coloring executable completion-ignored-extension files

[Andrew M. Scott]

Dired isn't coloring completion-ignored-extension files for cases where
execution permission bits are set and dired-listing-switches contains "F".

This appears true on Emacs-20.7, 21.3, and CVS emacs 22.0.50.1 (2005-03-23 
snapshot)

% emacs -q -no-site-file &

(setq  dired-listing-switches          "-alF"
       dired-ls-F-marks-symlinks       nil)
(global-font-lock-mode 1)

I'm using GNU gls 5.2.1 with
alias ls gls --color

C-d ~/

The 2nd file down isn't getting face dired-ignored, but the 4th one down is.
  /home/mine
