Info needed in 1.6.x STATUS file

Hi devs. Going through the 1.6.x. STATUS file, I am finding some items
that could do with a better description or justification to make it
easier to evaluate them. Can anyone provide information on the

> * r934599, r934603

> Opening the DB twice (and overwriting the handle) is undesired.

Why is that undesired? I mean that as a serious practical question -
obviously it's theoretically redundant but that in itself doesn't
necessarily matter. What is the user-visible effect of the problem, and
of the proposed change?

What is the purpose and effect of the change proposed for back-port?

Ah, I already put my concerns here.

> * r916286, r917512

What is the purpose and effect of the change proposed for back-port?

(It was me who added the question marks, some time ago.)

> Notes:
> This backport depends on the r878590 group only for the conflict free port.
> Justification:

How bad is the old error message? How much better is the new one? An
example might help. Does the change have any other effect?

Commit happens in the slave? That's certainly and obviously wrong. But
I don't understand what you mean by "the configured slave url has the
*encodable* characters".

> Votes:

> * r935631
> Fix one of the sanity checks in the 'svn merge --reintegrate' logic.

What check? What did it do? What will it do after this change?

OK, I've looked at this one, and it appears that the check to ensure the
source and target are in the same repository was not being checked (it
was comparing target-repos with target-repos), and this change will make
it return an error if they are in different repositories, as was
intended. I'm not sure exactly what would happen if this condition were
not caught.

(Here's an example of a good description and justification.)

> * r950445, 950468
> Fix for issue #2591 "'svnadmin hotcopy' does not replicate symlinks".

Length of time is not really a justification.

All of these issues exist in 1.6.x, that's why the fixes are proposed
for back-port.
