That one's probably mostly about the issue mentioned in the other
commit you identified. Without %top, it's impossible to make a
standalone flex module honor the rule about thou-shalt-have-no-
other-includes-before-postgres.h. So embedding it in some other
file was originally a necessity for that. Now that we know how
to fix that, it's just a matter of making sure that any other stuff
the scanner needs is available from a .h file.
