You're right. I forgot to mention that.

It confirms my feeling that support_zipped should not be enabled by default. It
asks for too much control over too many things.

I'll probably do that.

No, options are in the config table. C is for constants. (Identifiers in
constants.tlu that look global are accessed (read-only) via the C table outside.
This is a pretty standard Lua trick, but I should probably document the fact.)

Documenting undocumented facts counts as changing documentation :-)

Hum, that's probably because I always forget they exist :-) Do you see any
practical use case for configuration files here? I'm slightly reluctant to add
yet another level of configuration files for texdoc...
