Fix documentation bug related to backup history file.

MasaoFujii · MasaoFujii · commit 09879f753635 · 2018-06-27T00:49:47.000+09:00
The backup history file has been no longer necessary for recovery since the version 9.0. It's now basically just for informational purpose. But previously the documentations still described that a recovery requests the backup history file to proceed. The commit fixes this documentation bug. Back-patch to all supported versions.
