longest_ancestor_length(): take a string_list argument for prefixes

Browse Source 
Change longest_ancestor_length() to take the prefixes argument as a
string_list rather than as a colon-separated string.  This will make
it easier for the caller to alter the entries before calling
longest_ancestor_length().
