Executing glob command with repeated 'directroy' switch gives misleading exit message. For example:
input: glob -dir / -dir /home
output: "-directory" cannot be used with "-path"

The same is in -path switch.

Also with -path.

% glob -path / -path / q
"-path" cannot be used with "-directory"

This situation demands some tests be written.

Attached is a patch that passes the Tcl tests.
