\\ -> \e

Bump date for previous. Use mdoc macros.

Add example of using -w.

Use standard AUTHORS section header. From YOMURA Masanori in private mail
Sort sections if necessary. Use more/better markup.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22269, verified by myself.

Lots of minor fixes resulting from reading these man pages in detail.

Generate <>& symbolically. I'm avoiding .../dist/... directories for now.

Fix problem noted in PR 6649 (trailing whitespace on .Nm)

WARNSify, fixup .Nm usage

Fix broken uses of Dd. Both the mdoc and mdoc.samples pages agree:
.Dd is supposed to be invoked like:
.Dd month day, year
e.g. ".Dd January 25, 1989", rather than:
.Dd "month day, year"
which is what these pages did.

don't print 'Message:' prompt if stdin is not a terminal.
(from Masanobu Saitoh <saitoh@spa.is.uec.ac.jp> in pr 982.)
Also, fix usage string and manual page to note that width argument
for -w is _not_ optional.

file-static.

Use __dead

sprinkle static

Remove the \n and tabs from the __COPYRIGHT() strings.

Check that -w width is not above maximum. (It already checks for zero or
negative.) Using width above DWIDTH may cause overflow as noted by Gruzicki
Wlodek on bugtraq.

While here replace one use of 132 with DWIDTH.

Whitespace fix

Changed the type of data_table to be unsigned char[] instead of char[],
because it is initialized with values >= SCHAR_MAX. Also removed two
unnecessary bit mask operations. These changes do not affect the actual
behavior. Also replaced an "#ifdef notdef" with "#if 0". All these
changes are mainly for reducing lint(1) warnings.

Fixed buffer overflow with long command line arguments.

branches: 1.12.2; 1.12.4; 1.12.6; 1.12.8; 1.12.10; 1.12.12;
Remove uses of __P.

Back out last due to think o on my side: we don't start banner through
dm(6), so there's no setgid privileges to discard. Pointed out by
Joseph S. Myers <jsm28@cam.ac.uk>

Drop setgid privs passed from dm(6).
