d8499f2d8f Bug#17877 - Corrupted spatial index
CHECK TABLE could complain about a fully intact spatial index.
A wrong comparison operator was used for table checking. 
The result was that it checked for non-matching spatial keys. 
This succeeded if at least two different keys were present, 
but failed if only the matching key was present.

I fixed the key comparison.

d0c6eb885d Bug#14980 - COUNT(*) incorrect on MyISAM table with certain INDEX
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).

e515d7018f a proper fix for the bug #2298 Trailing whitespace inconsistently handled in WHERE clause.
<monty> ramil, in MySQL/MyISAM we should only strip end space, not 'space-like' characters.
<monty> This is according to SQL;  When doing a comparision end space and only end space are ignored.
