Actually a subtle change, as includes and anchors could previously
contain spaces. Possibly should still alow that, although I expect it's
never used.

In quickbook 1.6, nested documents default to C++, regardless of the
parent's source mode so that they are interpreted as if they are
standalone documents.

Imports were failing because doc info expected values. The process_state
stuff is too fragile, so instead just process the contents of a
conditional phrase and discard them afterwards. Still suppresses all
elements.

This is more consistent than it is at the moment. For the __FILENAME__
macro, use the path relative to the original file or the location last
matched on the include path. This ensures that the macro is consistent
no matter which directory you call quickbook from.
Also enable `__FILENAME__` in debug mode - so I can test this.
