C. Scott Ananian 5812413f11 Extend 'format' spec to include custom format strings.
Thanks to Thiemo Mättig for the suggestion and specification at
Wikimania 2016 in Esino Lario.

This is an extended version of Thiemo's original specification.  This
version also allows specification of "own line" properties for
templates; that is, whether the template should be preceded/followed
by a newline, as requested by James Forrester.
