- clarify the examples for the bench command
- typo in search.cpp
closes https://github.com/official-stockfish/Stockfish/pull/4710
No functional change

-/// bench 64 1 15 -> search default positions up to depth 15 (TT = 64MB)
-/// bench 64 4 5000 current movetime -> search current position with 4 threads for 5 sec
-/// bench 64 1 100000 default nodes -> search default positions for 100K nodes each
