Comment 4 for bug 1226558

Lua isn't an acronym :)

You can add a room to an area without specifying the coordinates - it is a
two step process in the API. Do you mean to say whenever it will show in
the mapper if the coordinates aren't set?

What is your motivation behind the all in one function? We still need to
have the stepped process available. You might not know the rooms
coordinates upon wanting to create it, for example.

Internal failure isn't a good error message :) better to actually say what
the problem is - it will help us and the users. We haven't got proprietary
data we don't want to expose, anyway.

I've recently instituted a better format for error messages - search for
pushstringf. It's desirable to follow examples there as they are most
explanatory format we've got so far - and an error message that explains
the situation better is the more desirable one.
