-------------------------------------+-------------------------------------
 The location assigned by the parser to `LHsModule`s is incorrect: it is a
 point span at (1,0) rather then a span encompassing the entire file.

 This was taken from #597, which also included a number of other similar
 issues, all of which are now resolved.
