Yes, it seems that COMMAND.COM doesn't try an extension if what you
type already has an extension (any extension).  This makes sense on
plain DOS, where there can be only one dot, but not under LFN.

Not for me, it doesn't: I just tried (on Windows 98).  If I type
"hello.world [Enter]", it says "Bad command or file name".  Only
hello.world.exe works.

You did try it from COMMAND.COM, yes?

That's not what COMMAND.COM does.  Try typing "foo" in a directory
where both `foo' and `foo.exe' exist, and see who gets called.
