Be careful when re-using %pf or %pF! I am not a native speaker but the sentence is hard to parse to me. Also I miss the word 'symbolic'. IMHO, it described that the output was a symbol name. What about something like? * - '[Ff]' %pf and %pF were obsoleted and later removed in favor of * %ps and %pS. Be careful when re-using these specifiers. Best Regards, Petr
