Well, ^C worked for me, though the terminal then would not respond to 
any other input.  Maybe that's what you meant by "it's entertaining".

Yes, this is a known issue.  It's the same old problem one would expect
to have on a system that relies on the filename to determine what it 
should do with the file.  You'd see something similar with a .bat/.exe 
file combination in Windows, unless I'm misinterpreting what you're 
saying..
