    450 #		3    ${VAR#pat} is the value of VAR with leading pat removed

    455 #			Including ${##${X}} where X='' or X='#'
    456 #		3.d	And ${#\#} is invalid (error)
    457 #		3.e	But ${##\#} removes a leading # from the value of $#
    458 #			(so is just $# as there is no leading # there)
    459 #		4    ${VAR##pat} is the value of VAR with longest pat removed
    460 #		4.a	Including ${VAR##} which removes the longest nothing
    461 #		4.b	Which in this case includes ${###} (so is == $#)
    462 #		4.c	But not ${##\#} which is $# with a leading '#' removed
    463 #			(and so is also == $#), i.e.: like ${###} but different.
    464 #		4.d	As is ${###\#} or just ${####} - remove  # (so just $#)
