Sections are, once again, eagerly entered.

When the section tracking code was rewritten a while back to simplify and iron out some bugs the order of evaluation was changed so that each new section was skipped on the first run through.
This had unwelcome consequences for some people.
This commit restores the original semantics (while maintaining the simpler, less buggy, new code).
