Fix assertion failure on line 713 of row0upd.c if there is a column prefix index and the last characters in the prefix are spaces: do not assume that the length of alphabetically equal strings is the same; fix a buglet which could cause InnoDB to think that a secondary index record was not locked though it had been updated in a way which did not alpahabetically change its value, e.g., abc -> aBc
