description:
various updates from <henrik%gulbra.net@localhost> / freebsd.  the list from Henrik:

bozohttpd.8:
    o Added -d flag to the man page
    o Moved -E flag in man page to keep alphabetic order
    o Grammar fix for description of -E flag in man page
    o Moved a word in the man description for the -f flag
    o Made -f imply -b as a backwards-compatible shortcut
    o Updated man description of -n to mention Lua scripts
    o Moved -z below -Z to keep the uppercase options first

bozohttpd.c:
    o Removed obsolete comment about ~user missing cgi-bin support
    o Removed "/* ARGSUSED */" lines; was that a macro or a reminder?
    o Added USE_ARG macro call for sig, which was otherwise not used
    o Added USE_ARG macro call for msg (only used if debug is enabled)

bozohttpd.h:
    o Fixed typo in the include guard (BOZOHTTOPD_H_ -> BOZOHTTPD_H_)
    o Renamed have_all to have_core; it didn't mean "all" options

content-bozo.c:
    o Added USE_ARG macro call for signo, which was otherwise not used
    o Made -f imply -b as a backwards-compatible shortcut

main.c:
    o Simplified -b text to be symmetric with that for the -f option
    o Updated -C text to make "suffix" explicit; it's better than "arg"
    o Changed to only show the -E description if have_user is true
    o Always show the -e option, which incorrectly used the -E logic
    o Renamed have_all to have_core; it didn't mean "all" options
    o Added three missing tabs for the description of the -G option
    o Updated -L text to make "prefix" explicit; it's better than "arg"
    o Updated -M text to make "suffix" explicit; it's slightly better
    o Added a previously missing description for the -n option
    o Documented the otherwise obscure valid types for the -T option
    o Shortened "username" to "user" to match the actual help text
    o Moved handling of -c below that for -C to standardize the order
    o Broke the enabling test for -C into two lines for consistency
    o Inverted the enabling test for -E; this is what was meant, right?
    o Removed the enabling test for -e, which should always be enabled

ssl-bozo.c:
    o Added USE_ARG for httpd, which is not used if SSL has been excluded
