Use ".Bx 4.0" rather than ".Bx 4" for clarity and consistency.
Both are correct, but "4.0" avoids the misunderstanding that we were
talking about any unspecified 4.xBSD release, and it is much more widely
used in our manuals.
Discussed with jsg@ in the context of other manual pages.

Drop an unnecessary #include

reminded by schwarze@

When there are multiple groups of functions with their own #includes
listed, the #includes in each group are independent, so that users
don't need to guess at possible carry-over.

Implement the WCONTINUED flag to the wait(2) family of syscalls and the
associated WIFCONTINUED macro as per 1003.1-2001. Adapted from FreeBSD.
A minor amount of trickiness is involved here. The value for WCONTINUED
is chosen in such a way that _WSTATUS(_WCONTINUED) == _WSTOPPED and the
WIFSTOPPED macro has been modified such that WIFSTOPPED(_WCONTINUED) !=
_WSTOPPED. This means we don't need to add an extra check to the
WIFSIGNALED and WIFSTOPPED macros. deraadt@ OK.

Another round of man page cleanup, this time to remove more hard sentence
breaks and getting rid of short lines, making these files easier to work with.

- change references to nil to null; tschroed@acm.org
- remove trailing spaces from end of lines
- add some .Dv
- change -1 to \-1, so `-' is taken as a negative sign
- other misc formatting fixes
