Oh, and if I comment out that ignore, it falls through and hits another
ignore:

dbg("received-header: unknown format: $_");

return;
A problem with how the code currently works is a return of undef can
explicitly mean two things: parsing failed, parsing wants to ignore the
header ...
I'd like to change the functionality so that undef means failed, and something
else means "ignore" (like return a hash with skipped=>1 or something).
BTW: The script I posted in a previous comment ... doesn't work
apparently due to the undef issue and a slight misreading of the code...
So ignore my comments about it.
