Is this a content-space page template? One added to a folder?

I suspect that this is due to a bug in content-space
page templates.  Most objects want to be the base for their
views.  Content objects that are themselves "documents"
want to treat themselves as their base.

The fix is pretty simple, although not as simple as it
should be.  There's a marker interface that should be
declared for objects like this that given them browser-
traversal adapters that give them correct interpretation
of URLs ending in / and bases.  Unfortunately, this interface
is in the wrong place. :( (This happened when some files
were rearranged a long tme ago.)

ZPT pages need to provide an interface named IFileContent.
Also, this interface needs to be moved to a different place.

Does anyone (contributor) want to fix this?
