Historically, there is "STOP WAL LOCATION" after "START WAL LOCATION",
and "STOP TIME"/"STOP TIMELINE" at the end.

Hm, no. I don't think that I'd want to expand the use of the backup
history file in the context of recovery, so as we are free to add any
extra information into it if necessary without impacting the
compatibility of the recovery code. This file is primarily here for
debugging, so I'd rather let it be used only for this purpose.
Opinions of others are welcome, of course.
