Check what the nesting rules actually render

The emphasis bomb checked only that the output was not empty, which it
never is, and its input never nests. No input reaches the ceiling on
inline nesting either, since an emphasis cannot hold its own kind, so
the check now proves the nesting that does happen. Past the quote
ceiling only the innermost text was looked for, and any x passed.
