My patch doesn't change the return value of pg_stop_backup(), it's still
the same as the return value of pg_switch_xlog(). Only a part of backup
history file (the file name including stop wal location) is changed.
Currently, the file name is wrong if stop wal location indicates a boundary
byte. This would confuse the user, I think.
