Removed another rebel reference by Sasha...

Because the user could issue the @code{FLUSH LOGS} command, we need to

know which log is currently active and which ones have been rotated out

and in what sequence. This information is stored in the binary log index file.

The default is @file{`hostname`.index}. You can use this option if you want to

be a rebel.

The default is @file{`hostname`.index}. You should not need to change this.

Example: @code{log-bin-index=db.index}
