for 2.95, I find it helps to pipe the output through a sed script to collapse
the template names.  ie

#!/bin/sed -f
s/,\([ ]*\)std::allocator<\([^>]*\)>//g
s/std::basic_string<char,\([ ]*\)std::char_traits<char>\([ ]*\)>/string/g
s/std::basic_string<wchar_t,\([ ]*\)std::char_traits<wchar_t>\([ ]*\)>/wstring/g

This wont work for 2.96, but its not needed as much.  (I just 2.96 wouldnt
prefix each continuation line the file name...)
