Speed, I think.  It's old code.

You shouldn't dump booleans at all because on different machines you
can end up with different sizes: note how mltex_p is handled.

There's some other stuff that seems off in the patch: web2c's
'dump_int(hyph_prime)' gets turned into 'dump_int(hyph_size)'; I'm not
convinced that is a good idea.

I may also end up suggesting somewhat different messages.
