Comments from Vladimir Oleynik influenced the final patch, and I also ripped
out the in-file changelog since it belongs here. At the time, it said:
/* Apr 15, 2004 Matthew S. Wood (mwood@realmsys.com)
*
* Implement '-b' (backup) flag.
* Implement '-S' (backup suffix) flag.
*
*
* Mar 16, 2003 Manuel Novoa III (mjn3@codepoet.org)
*
* Fixed bug involving -n option. Essentially, -n was always in effect.

This is a first attempt to improve the comments of getopt_ulflags.c.
Maybe under some aspects the text could be refined, but so
far it is already usable and should help people who "avoided getopt_ulflags as the pest" to understand how it works.
This patch was created with the help of
Vodz, the author of the code, who explained me patiently
how getopt_ulflags works
and with the help of
Paul Fox, who corrected my broken english.
So thanks and merits should go to them also.
The init applet will restart (re-exec) itsself when it
receives a SIGHUP. However, just before it enters its
main loop, it resets SIGHUP to either re-load the inittab
(or ignore it if no inittab is used). Thus preventing
the re-exec option from being triggerable.
This patch adds a signal handler for SIGQUIT for init that
always causes init to re-exec itsself (along with killing
anything else that might be still running).
