Log Message:
-----------
During validation, drop .br before a text line starting with a 
blank, rather than teaching each formatter individually to ignore
the .br in such situations.  That's simpler and also results in
better diagnostics.

Mark Harris <mark dot hsj at gmail dot com> reported 
that -T html got confused in particular.
