A couple ways to avoid such an issue in the future:

 * Always quote any wildcards that you aren't wanting to match files (i.e.
don't depend on your shell to pass non-matches as literal wildcards to any
program).  If you can ask your shell to return an error for non-matched
wildcards (instead of running the command), that can help get in the habit
(e.g. use zsh's "setopt NOMATCH").
 * Get in the habit of using --exclude=ARG so that unquoted wildcards are less
likely to match anything.
