Quite so.  Plus, what happens next is shell (and shell-option)
dependent.  Some shells always expand their args, so expanding a
non-matching arg causes the entire string to vanish (a very useful thing
in a script's "for" loop, but not on a command-line).  Other shells
complain about there being "no match" and refuse to run the command (I
have my interactive shell set to do that because it helps guard against
mistyped args).  Just FYI.
