Comment (by zeeshan.qazi@…):

 Sorry: the code block should appear as below:


 {{{
             //Old situation:
             // __________________________________________________
             //|            raw_mem         | old_begin | old_end |
             //| ___________________________|___________|_________|
             //
             //New situation:
             // __________________________________________________
             //| old_begin |   new    | old_end |  raw_mem        |
             //|___________|__________|_________|_________________|
             //
             //Now initialize the rest of memory with the last old values
             //All new elements correctly constructed, avoid new element
 destruction
             const size_type raw_gap = s_before - before_plus_new;
             if(!value_traits::trivial_dctr){
 }}}
