Commit Message

STATE_FIELD describes a parser state that can handle any part of a
kerneldoc comment body; rename it to STATE_BODY to reflect that.

The $in_purpose variable was a hidden substate of STATE_FIELD; get rid of
it and make a proper state (STATE_BODY_MAYBE) instead.  This will make the
subsequent process_file() splitup easier.

I really wanted to avoid leaving behind any evidence that I've ever
reviewed perl, but my sympathy for you updating the script won. But just
barely.
