We have been hit several times in Django by this MySQL limitation when
wanting to extend the length of some indexed char fields. One example is
#19515.
I suggest to automatically limit indexes when the size of the indexed
field is too long to be completely indexed by MySQL. This auto-truncation
would be limited to single-indexed fields, because I don't see trivial
automatic rules when more than one field is indexed (proportional
shortening, maybe?).
