[texhax] Custom sorting of section names in CWEB

[Tomas Rokicki]

The best solution is to retitle your sections so one is not a prefix of the
other.
A section name of "type definitions", when it's obviously type definitions,
does not
help the reader all that much.

If you *really* can't bring yourself to do that, move the null to the end
of the name.
But ughh.
