A fix (bug #9756: mysql client failing on dumps containing certain \ sequences).
mysys/charset.c:
A fix (bug #9756: mysql client failing on dumps containing certain \ sequences).
As 'to_end' points to the last position we should use '>' comparison
instead of '>=' there.
'l' replaced with 'tmp_length' (in order not to mix 'l' with '1').
