But the IF_LINT part is AFAIU the _only_ part of the configuration
that the user needs to supply.  All the rest, including the forms to
evaluate, doesn't have to be in file-local variables.  Right?  And a
list of strings can easily be a safe local variable, so if you devise
a variable that will accept lists like '("IF_LINT"), it could easily
be specified without prompting those annoying questions.

Moreover, we could support these particular macros by default: I doubt
that Paul invented them for Emacs, and even if he did, they are by now
probably used elsewhere, so it should be good to have their support
built-in.

Am I missing something?

Thanks.  I hope the considerations above will allow to restore the
feature soon.
