Merge change from MySQL (this fixes the failing innodb test):

ChangeSet@1.1810.3601.4, 2008-02-07 02:33:21+04:00, gshchepa@host.loc +9 -0
  Fixed bug#30059.
  Server handles truncation for assignment of too-long values
  into CHAR/VARCHAR/TEXT columns in a different ways when the
  truncated characters are spaces:
  1. CHAR(N) columns silently ignore end-space truncation;
  2. TEXT columns post a truncation warning/error in the
     non-strict/strict mode.
  3. VARCHAR columns always post a truncation note in
     any mode.

  Space truncation processing has been synchronised over
  CHAR/VARCHAR/TEXT columns: current behavior of VARCHAR
  columns has been propagated as standard.

  Binary-encoded string/BLOB columns are not affected.
