libxo-0.8.4
- avoid anchor width optimization when we have a custom formatter (https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=221130)
- make "{[:/18}" do the right thing (also allows "{[:/%s}", wide ? 40 : 10)
- Can't skip anchor formatting in non-display styles
- add test case for {[:/18}
- add upload-xohtml-files to 'make upload'
