- void anchor width optimization when we have a custom formatter (https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=221130)

- Can't skip anchor formatting in non-display styles
- add test case for {[:/18}
- add upload-xohtml-files to 'make upload'
0.8.3:
- xohtml: Add "-w" option to pull support files from gh_pages
- Add "upload-xohtml-files" target to publish support files in gh_pages/
- add HISTORY/AUTHORS section to man pages
0.8.2:
- xohtml: Add div.units as standard CSS text
- Don't treat values as format strings; they are not
- add "-p" to "mkdir -p build" in setup.sh
- add test case for {U:%%} (from df.c)
- detect end-of-string in '%' and '' escaping
- make xo_simple_field, for common simple cases
- xohtml: nuke "n" in "echo" commands
