Yes, learn to avoid wildcards in command parameters at all costs. But we
both know that is not satisfactory.
And it's not much help when someone types in:
and the program has to try and clean up the mess, if it can see it is a
mess. But remember:
There might be some irate users out there if it can't detect a simple
user error like that.

OK, I understand. Having a program launcher indiscriminately transform
input A into A' is /much/ better than having it done by the program,
even if the program doesn't want it and it is not meaningful.
The fact that you also lose format information (is it three parameters,
or one parameter transformed into three) is an extra bonus.
This is clearly much better than any other scheme because:
(1) It's Unix not Windows; everything in Unix is always better and
always make sense.
(2) There have been 40 years of it working this way and there have never
been any problems. (That is, 40 years of writing programs with
stultified command line interfaces to make sure that is always the case.
[As for 'problems' such as the 'cp *.c' one, that's a feature!]
