thanks for eval-after-load but...

[Joe Corneli]

After running this

(eval-after-load "sh-script" 
                 '(put 'sh-maybe-here-document 'disabled t))

and opening a bash script with this in it

grep "<<$SF>>" $HOME/.todo/$TODOLIST > $HOME/p
ade=$?

`ade=$?' and following text is still in sh-heredoc-face

So I guessed wrong, and disabling that command is not enough.
Any guess why? And how to actually change this behaviour?
