* An actual file may contain more than one map. However, if we do things
* in the normal yacc way, i.e. aggregate all of the maps into a list and
* let the caller find the map it wants, we end up scanning and parsing a
* lot of unneeded maps (in the end we always just need one).
* Instead of doing that, we make yyparse return one map at a time, and
* then call it repeatedly until we find the map we need. Once we find it,
* we don't need to parse everything that follows in the file.
* This does mean that if we e.g. always use the first map, the file may
* contain complete garbage after that. But it's worth it.
