I see ... it only returns nothing if the parameter contained a * or ?
I remember having some discussions regarding this and we agreed that
even this should survive the cmdline globbing.
So that you could print
Cannot open file *.txt
or
No files match the *.txt mask
If you happen to have several masks with different meanings it might
be good to be able to say which one did not return anything.
And it may not of course :-)
I was told this is the behaviour of the Unix shells ...

There's one more bad thing about this code. Suppose the script was
called like this
script.pl "hello world.doc"
then the @ARGV = ( 'hello world')
but the line above will set @input_files to
( 'hello', 'world.doc' )
Not very usefull :-)
