Yep. That was my own response, so I double checked, re-compiled,
re-ran...same result.
My initial attempt, before receiving your email, was to comment the SGML
call out altogether, also with the same result.
The release for Display.cc is:
#if RELEASE
static char RCSid[] = "$Id: Display.cc,v 1.54.2.27 2000/02/17 16:46:25
grdetil Exp $";
#endif
Perhaps it has something to do with how HTML.cc treats META values? The
changes you've specified below change this behaviour.

Closer. When I do this, the line is no longer truncated. However, '<'
becomes '&lt;' in the search template. EG:

Obviously, I need to find out where this is happening. Sorry for the c++
tutorial request--too many years since I coded in a unix environment--but
how do I set the debug level when 'make'ing, and where does output sent to
cout go?
Thanks,
Patrick.
