- WRITING: updated
- docbook/literals.ent: trimmed the "default" text that is displayed if
we did not yet document an element.
- bin/refs-autogen: if 'purpose' line is missing, but 'description' is there,
then make purpose = " (partly documented)".
- the rest of files: fixes and a lot of new variables (most of which need
more work, check out tmp/missing after running 'make refxmls')
