Ok, now I understand what you meant by that particular point.
Could you give a self-contained and clear explanation of
why this is a problem?
Because it initializes Font Lock for the wrong major mode. Currently,
any attempts to correct this undo prior calls to
font-lock-{add,remove}-keywords that passed nil for MODE. Some of
these calls we actually might _want_ to undo, but others not, according
to some as yet undocumented rules.
Basically, it appears to me that the way Font Lock handles calls to
font-lock-{add,remove}-keywords that pass nil for MODE is flawed.
Sincerely,
Luc.
