Merging copy operations

Hi!

I'm refactoring code and in that context I moved parts of one file to a
separate file, so I copied trunk/A to trunk/B and then hacked the two so that
each contained one part of the code. Then, when the whole works again, I
commit the whole in a commit. First question here: I consider that a normal
approach that should be supported, any objections here?

Then, lateron, I want to merge the changes. I then merge the revision from
trunk to the stable branch. What I noticed there is that in the branch, the
"copy from" property of the newly-created file "stable/B" points to "trunk/A",
while I would have expected it to point to "stable/A" instead! Second question
here: In what case does the existing behaviour make sense? I'd say that when
merging, such copy-from paths must also be translated to the new tree.
However, if the path was outside the "from" tree, it shouldn't be translated,
so there the current behaviour would be expected.

What I'm not sure is if this has an effect on mergeinfo, I haven't actually
tried that, so I'm guessing here. What I think is that if "trunk" at some
point acquired any mergeinfo, that mergeinfo implicitly applies to "trunk/B",
too. If I now copy that file to a branch, it will preserve that mergeinfo
(right?) so that now the file and the rest of the branch explicitly have
different mergeinfo properties. At least I believe this can happen, which
would be bad, because you typically want the mergeinfo to be restricted to the
root of the branch.

Is this a bug or am I doing something wrong?

Uli
