This line is a bit long.  Even if might look a little weird, I think
it's better split in three.

Try Strfnd mod_search_paths{modpath}.  The normal bracket style
confuses C++, because it can also be parsed as a function declaration.

This is a somewhat weird interface imo.  I think core.get_modpath
should be the first element of core.get_modpaths and documented in that
way, so that any GUI that deals with "all known mods" needs to simply
call the latter, whereas any GUI that deals with installing can
comfortably use either the former or whatever Lua has for car.  WDYT?

Otherwise LGTM.
