PageTemplates lacking traceback info in 2.10+

The Zope 2.9 code had traceback support in "PageTemplate.pt_render"
which told us which template was affected.
As you can see in the traceback above, at least this traceback support
is lost in Zope 2.10.
Looking at Zope 2.11, the traceback support above seems to have
been resurrected.

Furthermore, I could not find the equivalent of the transback
support which formerly was in "Expressions.py" (I found the one
corresponding to "TALES" and "PythonExpr").

This report is incomplete and missing the actual traceback. From my understand the missing traceback support has been added back in 2.11 solving this problem.
