Hi Nate,

thanks for the report.

Said snippet is a doc-tagged LSR-snippet.
While the LSR still runs 2.18.2 the proposed fix will work for this
version and upstream.
Thus I fixed it inside LSR.
http://lsr.di.unimi.it/LSR/Item?id=681
With next LSR-import the corrected version will be present in NR.

Regards,
  Harm
