- clean up escape sequence handling, creating three classes:
(1) fully implemented, or parsed and ignored without loss of content
(2) unimplemented, potentially causing loss of content
see textproc/mgdiff(1) for nice examples
(3) undefined, just output the character -> perhaps WARNING
-- The \t escape sequence is the same as a literal tab, see for example
- the ASCII table in hexdump(1) where
- .Bl -column \&000_nu \&001_so \&002_st \&003_et \&004_eo
- .It \&000\ nul\t001\ soh\t002\ stx\t003\ etx\t004\ eot\t005\ enq
- produces
- 000 nul 001 soh 002 stx 003 etx 004 eot 005 enq
- and the example in oldrdist(1)
-
- look at pages generated from reStructeredText, e.g. devel/mercurial hg(1)
These are a weird mixture of man(7) and custom autogenerated low-level
roff stuff. Figure out to what extent we can cope.

- check compatibility with Plan9:
http://swtch.com/usr/local/plan9/tmac/tmac.an
http://swtch.com/plan9port/man/man7/man.html
- a column list with blank `Ta' cells triggers a spurrious
start-with-whitespace printing of a newline
-- double quotes inside double quotes are escaped by doubling them
- implement this in mdoc(7), too

- empty phrases in .Bl column produce too few blanks

Found in mount_nfs(8) and exports(5), search for "Appendix".
+- Trailing punctuation after .%T triggers EOS spacing, at least

- The same happens with .Pp just before .El, see bgpd.conf(5).
- Also have `It' complain if `Pp' is invoked at certain times (not
- -compact?).
-
- .Pp between two .It in .Bl -column should produce one,

+ An easy partial fix would be to just skip the first word if it starts
+ with a dot, including any following white space, when measuring.
- The \& zero-width character counts as output.
That is, when it is alone on a line between two .Pp,
we want three blank lines, not two as in mandoc.
-- When .Fn arguments exceed one output line, all but the first
- should be indented, see e.g. rpc(3);
