Fixed in src/uk/me/parabola/mkgmap/reader/osm/xml/Osm5XmlHandler.java
revision 1466.

This only affects style files containing apply role=blah {} constructs.
Only one role of the member element would be recorded.  I plan to address
that by defining Relation.roles as a poor man's MultiMap, similar to what
I did in Osm5XmlHandler.deferredRelationMap.  (Only the role information
will be lost.  All relation members will be recorded in order, because
otherwise apply_once would not have been necessary.)
