Vista - Known bug? arbitrary switch options work.

Is this a known bug? You can specify arbitrary switch options whose initial
parts match specific options.


PS> switch -c ('abc') {'abc' {"one"} 'ABC' {"two"}}
one
PS> switch -cf ('abc') {'abc' {"one"} 'ABC' {"two"}}
one

Yes. This looks like bug. In current implementation, we just match the first
character. Please post a bug on this.

Whoa, what's with the -cf? What option does that map to? Surely
not -casesensitive. And surely not -casesensitive -file. What gives??

Yep; only the first character of the option is examined. So
even -caseINsensitive is interpreted as -casesensitive.

This is a known bug. It's actually been around for a while. It just wasn't
considered serious enought to fix for V1.
