Implementing a new option `kill-as-displayed' might help to make
the behavior of killing/yanking of invisible text more natural.
However, there are other problems with invisible grep markers like
isearch failing to find a string with invisible markers inside.

Since no one likes invisible grep markers, they should be deleted
from the grep buffer even at the cost of losing the ability to restore
their highlighting after saving and reloading the grep buffer, or even
after modifying the lines with grep matches.

[There were a few problems with deleting grep markers with font-lock
machinery.  I will take care of that.]
