Document the new argument parser for sleep(1) and SIGINFO behaviour.
Remove higlight for the unportability notice.

MFC after: 3 weeks

Add the new standard EXIT STATUS section where appropriate.
Sort standard sections in the (documented) preferred order.

/*- or .\"- or #- to begin license clauses.

Remove clause 3 from the UCB licenses.

OK'ed by: imp, core

Sort sections, use Ex macro in Diagnostics section, point out that the first
example only works with csh(1).

Add History section. sleep appeared in v4.

mdoc(7) police:

Avoid using parenthesis enclosure macros (.Pq and .Po/.Pc) with plain text.
Not only this slows down the mdoc(7) processing significantly, but it also
has an undesired (in this case) effect of disabling hyphenation within the
entire enclosed block.

Prepare for mdoc(7)NG.

Remove more single-space hard sentence breaks.

Restore reference to sleep(3).

Let sleep(1) handle fractions of a second (up to nanosecond).

This is a conservative change. It does the same thing in weird
cases like the old one. For example, 'sleep abcd' still sleeps
for zero seconds. `sleep 10.a' and `sleep 10.05aa' do the best
and not abort (ie: 10.a == 10 seconds, 10.05a == 10.05 seconds).

$Id$ -> $FreeBSD$

Describe proper signals behavior rather than just removing it.
Remove obsoleted reference to alarm(3).

Submitted by: bde

There is no special handling for SIGALRM as
sleep(3) is implemented using nanosleep(2).

Various spelling/formatting changes.

Submitted by: Philippe Charnier <charnier@xp11.frmug.org>

Correct use of .Nm. Add rcsid.

Describe signals behaviour now

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Sort cross references.

Cleanup man page and -Wall cleaning.
