Deletes on a big index could crash the index when it needs to shrink. Put a forgotten negation operator in. No test case. It is too big for the test suite. And it does not work with 4.0, only with higher versions. It is attached to the bug report.

For "count(*) while index_column = value" an index read is done. It consists of an index scan and retrieval of each key. For efficiency reasons the index scan stores the key in the special buffer 'lastkey2' once only. At the first iteration it notes this fact with the flag HA_STATE_RNEXT_SAME in 'info->update'. For efficiency reasons, the key retrieval for blobs does not allocate a new buffer, but uses 'lastkey2'... Now I clear the HA_STATE_RNEXT_SAME flag whenever the buffer has been polluted. In this case, the index scan copies the key value again (and sets the flag again).

Removed the assumption of a certain key order. Since 4.1, keys are padded with blanks for comparison. Hence, shorter keys sort behind longer keys, if the data bytes have values below BLANK.
