Subject: [PATCH] symtable: Only consider first lv:rate ancestor for parent
 (bugfix)

This is a situation that should never happen (I haven't yet determined
whether or not we should support this type of thing in the future), but when
it does, do something intelligent.

* src/current/include/preproc/symtable.xsl (preproc:symtable)[c:*[@generates]]:
  Consider only first ancestor lv:rate.
