[MKDoc-dev] Template error on the mkdoc-1-6 branch

[Sam Tregar]

Hello all.  I'm doing a clean install from the latest on the mkdoc-1-6
branch.  After a few minor problems things seem to be working, but
some pages seem to be missing CSS styles (they're all white with
little formatting).  For example, /.account.subscribe.  Looking at
view souce I see a long Petal error (attached).

The source of the error appears to be this line (68) in
templates/fragments/head_public/en.html:

   petal:condition="true parent_uri"

This was added recently (on January 17th by Chris).  Removing it and a
similar line later on for "root_uri" fixes the problem, but I doubt
that's the right fix.

Taking of the goggles for a minute, maybe it's just a missing colon?
Adding a colon after both trues seems to work too.
