Update from libxo-0.8.1 to 0.8.4:
0.8.4:
- void 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'
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
- rename "format" to "fmt" for consistency; same for "str" to "value"

Import to 0.6.1
0.5.0:
document "trim" modifier
add xo_emit_field functions
Add xo_set_file{,_h} functions
Fix LIBXO_* variables; add -L and -I as needed
add --disable-silent-rules and an explicit make; s/PACKAGE-NAME/PACKAGE_NAME/; add /download/ to 'url'
fix silliness where xo_flush_h emitted closing tag (html); make the caller (xo_message) do it
flush after transitions; fix flush call in xo_do_emit
mkdir the version-specific packaging dir
use "XO_" instead of LIBXO_

0.6.0:
Add --with-retain-size to set the size (in bits) of the retain hash buckets
Add The Argument Modifier ({a:})
Add retain and no-retain to --libxo
autoconf: Add test for monitor.h
Document quote heuristic
go deep with nroff backslashes
Use "ULL" for 32 bit check
add xo_retain_clear and xo_retain_clear_all
docs: combine two 'handles' section; move command line argument section
handle GETTEXT when msgfmt isn't where it's supposed to be (FreeBSD)
make 'retain' a flag (XOEF_RETAIN) instead of a role; it's simpler, and doesn't feel as tacky. "{R:}" was painful to document, which means it's painful to use.
new xo_emit_f functions
nuke some unused UNUSEDs
test code: path must be static
update test cases

0.6.1:
fix version number (missed a commit during new-release)
