%A section name from section. For group components, print group name too.
%B file name from bfd. For archive components, prints archive too.
+
+ Note - because these two extra format specifiers require special handling
+ they are scanned for and processed in this function, before calling
+ vfprintf. This means that the *arguments* for these format specifiers
+ must be the first ones in the variable argument list, regardless of where
+ the specifiers appear in the format string. Thus for example calling
+ this function with a format string of:
+
+ "blah %s blah %A blah %d blah %B"
+
+ would involve passing the arguments as:
+
+ "blah %s blah %A blah %d blah %B",
+ asection_for_the_%A,
+ bfd_for_the_%B,
+ string_for_the_%s,
+ integer_for_the_%d);
