This does *not* fix the issue in #3154, but makes it fail!()
instead of (maybe?) reading uninitalized memory.
Run the same tests for make check on all platforms

This target is no longer run in automation; it's for developer convenience, so
it should really run everything.  Also ensure that `check-all` is a superset

Add support for backgrounds on inline elements. Fix fixup() by removing it.

The code that managed ranges was buggy - failing on edge cases
such as a span within a span. I have refactored the code so that the
context information for inline formatting can optionally be stored
within a fragment. This seems cleaner to me, and fixes the bugs
encountered when making these changes by removing the need for
the fixup() functionality (and ranges).
