  Bug #26642: create index corrupts table definition in .frm
    
    Thanks to Martin Friebe for finding and submitting a fix for this bug!
    
    A table with maximum number of key segments and maximum length key name
    would have a corrupted .frm file, due to an incorrect calculation of the
    complete key length.  Now the key length is computed correctly (I hope) :-)
    
    MyISAM would reject a table with the maximum number of keys and the maximum
    number of key segments in all keys.  It would allow one less than this total
    maximum.  Now MyISAM accepts a table defined with the maximum.  (This is a
    very minor issue.)
