…r read()s
The two buffer-based overloads read(std::vector<DataType>&, pid, buf,
bsz) and read(std::vector<const char*>&, buf, bsz) returned the
leftover bsz after the loop instead of the number of bytes written,
contradicting the documented contract ('success returns the number of
bytes read'). Accumulate total bytes written and return that, matching
the read(DataType, std::vector<pid_t>&, ...) overload.
