Subject: [PATCH] BUG#21459 - myisam_ftdump gives bad counts for common words

This problem affects myisam_ftdump tool only.

For fulltext index positive subkeys means word weight, negative subkeys
means number of documents in level 2 fulltext index.

Fixed that document counter was not properly updated for keys having
level 2 fulltext index.

No test case for this bug.


myisam/myisam_ftdump.c:
  For fulltext index positive subkeys means word weight, negative subkeys
  means number of documents in level 2 fulltext index.

  Fixed that document counter was not properly updated for keys having
  level 2 fulltext index.
