: * tmac/groff_mdoc.man: Document new -width and -column syntax.
: Some other minor fixes.
: * tmac/an-old.tmac: Add `AT' and `UC' macros.
Fold -xwidth functionality into -width. .Bl now tests whether
string immediately following a leading dot starts with a valid
macro name.
Added similar functionality to the -column list's column width
specifiers. For example, the following now works as expected:
.Bl -column ".Va hw.crusoe.percentage" ".Vt integer" "Changeable"
.It Sy "Name\tType\tChangeable\tDescription"
.It Va hw.crusoe.longrun Ta Vt integer Ta yes Ta "LongRun mode:"
.It Ta Ta Ta "0: minimum frequency mode"
.It Ta Ta Ta "1: power-saving mode"
.It Ta Ta Ta "2: performance mode"
.It Ta Ta Ta "3: maximum frequency mode"
.It Va hw.crusoe.frequency Ta Vt integer Ta no Ta "Current frequency (MHz)."
.It Va hw.crusoe.voltage Ta Vt integer Ta no Ta "Current voltage (mV)."
.It Va hw.crusoe.percentage Ta Vt integer Ta no Ta "Processing performance (%)."
.El
This is especially useful for groff devices with variable width
fonts, like -Tps or -TX100.
- .Fn and .Fc now print a final semicolon (`;') after a
function declaration in the SYNOPSIS
- .%I implemented
- .At outputs ``AT&T UNIX'' if called without arguments
- minor cleanup

- spell the abbreviation of 1003.1 as ``POSIX.1''
- fixed the description of -p1003.1-90; it was sold as ISO/IEC 9945-1:1990
- removed -p1003.1b; it only existed as 1003.1b-1993 (-p1003.1b-93), and
is part of 1003.1 since 1003.1-1996.
- replaced -p1003.1g (project) with -p1003.1g-2000 (approved draft)
- changed abbreviation of -isoC from ``ISO C'' to ``ISO C89''
- removed -iso9899 alias for -isoC
- IEC was missing from some names
- added abbreviation for -susv2 (``SUSv2'')
If the -tag list definition didn't have a -width modifier,
the first .It call was supposed to set the width depending
on the first argument type; if it is a macro name, use the
macro's width value; otherwise, use width value of `No'.
The following two lists should produce identical output:
.Bl -tag -width Er -compact
.It Er EINVAL
invalid argument
.El
.Bl -tag -compact
.It Er EINVAL
invalid argument
.El
If the outermost -tag list definition did't have a -width
modifier, the .It elements of inner lists might not work
(producing a list where each successive element `walks' to
the right).
Example:
.Bl -tag -compact
.It outer
.It outer
.Bl -tag -compact
.It inner
.It inner
.El
.It outer
.It outer
.El

default .Ar argument as an end-of-sentence character.
Example:
.Ar
foo
Produced:
file ... foo
Now produces:
file ... foo
2. Fixed an off-by-one bug in the .It macro for the -hang lists.
Example:
.Bl -hang -width 8n -compact
.It 1234
OK
.It 1234567
OK
.It 12345678
BUG
.El
Produced:
1234 OK
1234567 OK
12345678 BUG
Now produces:
1234 OK
1234567 OK
12345678 BUG

2. Disable recognition of end-of-sentence characters in text-type
macro arguments.
3. Fix the missing space bug when an end-of-sentence character was
followed by another punctuation character.
4. Fix the bug where hyphenation was left disabled after .Re.
