with "-replace"  It tries to detect "-rtrue" or "-rfalse", which is the short
option + the boolean value for it. The ConvError is then caused by
"to!bool("eplace")".

I'm not sure if this report is valid but it's still possible to throw a better
exception with "expected true or false following simple option" or something
like that.

Maybe you can change the report title. "Better error message for short option
followed by wrong bool string".... + set it as enhancement, assuming you'd
agree that the real problem is that of course.
