- * severalnames() - A hack to determine if more than one name is
- * specified for a /M argument. The presence of
- * a pattern is taken to mean that there is more
- * than one name (even if it doesn't match anything!)
- *
- * Doesn't report a malformed pattern, as it will be
- * caught by a subsequent call to a pattern matching
- * function like foreach().
