Now if a file is listed as a specific entry, it will not *also* be

contain a negative value (as would be needed in the 'kill' commmand).
I still need to write man-page update before MFC-ing.
This started by rewriting the get_pid() routine. Later I looked at
what OpenBSD has, and included a few ideas from their send_signal()
routine. So, parts of this change are from OpenBSD, even though
OpenBSD does not actually have a 'U' flag.

need to be rotated. This would be used by some other command that decides
the given log file(s) should be rotated, but wants the "how" of that rotation
to be determined by entries to newsyslog. Wes expects to change syslogd to
take advantage of this. Man page will be updated after we're sure this is
all working the way we want it to.

`J' flag means that newsyslog should wait for previously started compression
jobs to complete before starting a new one for this entry. When it is used
along with the `G' flag, in the case when several logfiles match the pattern
and should be compressed, the newsyslog will compress logs one by one,
ensuring that only one compression job is running at a time.
This prevents newsyslog(8) from overloading system by starting several
compression jobs on big files simultaneously.

the specified filename of the log to be rotated is in fact shell glob
pattern. In this case, all files matching this pattern will be rotated
using the same options. Useful in the case when there is no pre-defined
name for the logfiles (e.g. xtradius, samba etc).

Although they sound the same, since both of them rotate logs at the

Add the much-needed and long-desired ability to force the log rotation
to take place on a specific day or time, and document same. This works
by extending the syntax of the `when' field to allow a restricted
ISO 8601 time specification, and performing the log rotation if newsyslog
is run during the same hour as is specified.
