unknown 5a1b7ddb68 Partial rollback of fix for bug #30059: End-space truncation is inconsistent ...

or incorrect.

For better conformance with standard, truncation procedure of CHAR columns
has been changed to ignore truncation of trailing whitespace characters
(note has been removed).

Finally, for columns with non-binary charsets:

1. CHAR(N) columns silently ignore trailing whitespace truncation;
2. VARCHAR and TEXT columns issue Note about truncation.

BLOBs and other columns with BINARY charset are unaffected.
