[Bug libstdc++/60936] [5/6 Regression] Binary code bloat with std::string

Hi!

There's a minor failure in the (patched) function __concat_size_t (within
snprintf_lite.cc):

size_t __len = __out - __cs;

Calculates the remaining/unsused characters in the buffer __cs!
Therefore the resulting string is (mostly) malformed/truncated.

... should be ...

size_t __len = __cs + __ilen - __out;

BR,
Markus
