Ooops... my lengthy email of T23:34 was unwantedly sent. A shorter
version with only the conclusion and w/o all the details of my
investigation is above.
Anyway, Philipp's patch is what I had in mind as a quick fix.
OK, I've pushed this commit as c3813b2aa8d2f5a625195fdbbfe6a01a602d7735.
don't think that this is a good solution not to factorize code when
possible. Factorizing makes it more maintainable.
Agreed. Note that there's a third place in Emacs that parses a subset of file-local variables: lread.c, to detect the lexical-binding variable when loading ELisp files. Ideally that would be merged as well.
