OK.  Thanks for the explanation.  You've taught me something new...

Yes, perfect sense.  Thanks, Greg.  It never occurred to me to "roll my 
own" commands by aliasing a command and my preferred options (I know 
this is lame, but UNIX gets cooler all the time!).  Now that I 
understand that scenario, it makes perfect sense that you would have to 
allow for the possibility of an option being "set twice", once by the 
alias and then again as an actual commmand line argument.

And in case you're wondering, no, I don't type out the commands all the 
time.  But I use scripts with hard-coded options, so this scenario you 
described just never materialized in my head before.  This alias method 
is much more flexible, while being simpler to boot.  Cool, thanks, etc...
