======Synopsis:======
$__numwords__(<word list>)

======Technical:======
This function serves as a replacement for the $#var notation when you
want to count the words in a string not held in a variable.

======Practical:======
This function is used to count the number of words in an arbitrary
string.  Normally, you could get this value with the $#var form, but
that doesn't work for parameter expandos or function return values.

======Returns:======
number of words in given string

======Examples:======
<file>
$numwords(hello there bob)                returns 3
$numwords()                               returns 0
</file>
