WL#1900 "When CHECK TABLE or ANALYZE TABLE of a MyISAM table is killed

Browse Source 
by KILL or shutdown, do not mark the table as corrupted".
It is indeed more logical to leave the corruption flag unchanged.
This cannot be extended to REPAIR/OPTIMIZE as they make no backup copy
of the MYI. This patch was tested with KILL and mysqladmin shutdown
while a CHECK TABLE was running. Without the patch, the table becomes
unusable (can't INSERT to it, error 145). With the patch, no.
