* RETURNS
* Success: The nth delimited parameter found in s
* if start != NULL, *start points to the start of the param
* if end != NULL, *end points to the end of the param
* if start != NULL, *start points to the start of the param (quotes maintained)
* Failure: An empty string if the param is not found.
* *start == *end == NULL
* *start == NULL
*
* NOTES
* Return value is stored in static storage (i.e. overwritten after each call).
* Specify 'start' and/or 'end' to include delimiting double quotes as well, if any.
* By default, the parameter is returned with quotes removed, ready for use with
* other API calls, e.g. c:\"a b"\c is returned as c:\a b\c. However, some commands
* need to preserve the exact syntax (echo, for, etc) hence the raw option.
