[PATCH] Basic_string::insert

[Paolo Carlini]

Sorry,

there is a small error in the tentative Changelog: insert(__pos, __s) already calls
insert(__pos, __s, __n) and its behaviour is affected indirectly.

Cheers,
Paolo.

        Optimize by avoiding temporaries and working "in-place" when possible.
        (insert(__pos1, __str)): Call insert(__pos1, __str, __pos2, __n).
        (insert(__pos1, __str, __pos2, __n)): Call insert(__pos, __s, __n).
