One last comment, to explain this 0.5%: before my patch *nothing* of 
those append was
inlined: nothing of append(const _CharT*, size_type) because it just 
called the heavy _M_mutate,
and nothing of append(const basic_string&) because was defined out of 
line. Therefore that 0.5%
easily accounts for the conditional and a bunch of assignments that now 
constitute "the bulk" of
those functions (+ reserve, still out of line).
