Hi,

I fixed some bugs.

Perhaps yes, though current patch doesn't care about it.
I'm not sure if we really need the feature. Yes, as you say,
I'd like to also listen to everybody else.

So far, name of a backup history file consists of only
checkpoint redo location. But, in this patch, since some
backups use the same checkpoint, a backup history file
could be overwritten unfortunately. So, I introduced
bkpCount as ID of backups which use the same checkpoint.

Yes, this patch is testbed. We need to discuss more.
