Topic: getopts (command line arguments) continued

Subject: Re: command line arguments

Regarding getopts and the 'all arguments are proceded by a "-"':
What about arguments that can be on/off switches, or can be positive or
negative numbers? In other words, what is wrong with allowing '+' as an
indicator of arguments? There are some commands that use it already.

Incidently, what happens with getopts if the command line was
command -n -30
and:
Option n is fetched
option 3 is fetched
option 0 is fetched

(No well written program would do all this, but essentially, what happens
if an argument looks like a flag? Or have you never grep'ed for a string
beginning with -?)
