scan_comma_elt()

const char * scan_comma_elt ( const char ** pstr )

extern

Given a pointer to a (char *), return a pointer to the beginning of the
next comma-separated element in the string.  Advance the pointer given
to the end of that element.  Return NULL if at end of string.  Caller
is responsible for copying the string if necessary.  White space between
a comma and an element is ignored.
