I did both -<n> and -w, and pushed it out in "next".

What we have:

        -<n>, -[ABC] <n> (and -[ABC]<n>)
        -E
        -G
        -H (but it is an no-op -- we always show name)
        -c
        -e (you can do multiple patterns now)
        -i
        -n
        -v
        -w
	-l

What are still missing:

        -I (easy)
        -L (probably a bit intrusive)
        -P (code is easy -- deciding dependency on pcre is OK is harder)
        -U (probably not so easy but may be useful)
        -Z (probably easy but is it useful?)
        -q (may not be worth doing)
        -z (easy but pointless)
	-F (dunno)
	-f (with the enhancement to do multiple -e, trivial to add this)
