This function parses a string containing a comma-separated
list of integers, a hyphen-separated range of _positive_ integers,
or a combination of both. The parse halts when the array is
full, or when no more numbers can be retrieved from the
string.
</p><p>
Return value is the character in the string which caused
the parse to end (typically a null terminator, if <em class="parameter"><code>str</code></em> is
completely parseable).
