Tagging *only* the changes in a branch

Branch A is my relatively static "core", gets re-used for multiple
projects, usually via export rather than checkout. However, for the
process being discussed here, I could go either way; for now, lets say
I check it out to wcA.

So I make my changes in the wcA tree - FYI if it helps, not
deleting/renaming or moving any directories or files, just adding
(using svn add of course) and modifying them.

OK, everything's working fine with my customisations, now I want to
upload *just my changes* to a new empty branch. The ultimate goal
being to be able to export branch A and then checkout only my modified
files right over the top of the whole tree, these files to be under
version control and not all the rest, using svn status -q to screen
out the files I'm ignoring.

An analogy from my old DOS days - from the top of a tree, "attrib -m
/s". Do your work, then when you want to copy out only the files that
are new or modified, "xcopy /aa /s" to a new tree. Am I dating myself
or what? <g>

Here's what I tried:

Copied Branch A to Branch B directly via URLs in the repos, checked
out from there, made all my changes and committed back up to B.

Created a new empty Branch C, checked that "nothingness" out to wcC,
and then did an "svn merge A B wcC". My logic was that the merge would
take my A->B changeset and create a new tree with just the changes in
wcC. But no, all I got was screens full of error messages about
skipping all the directories, skipping "missing target" for each file,
at the end got only one file that was new in the root.

This seems very strange to me, as if the merge command isn't able to
create new files and folders in the working copy? Do I need an empty
directory tree in wcC first?

Obviously I'm most interested in how to accomplish my objective, but
I'd also like to know what I'm not understanding about the merge
command, even if that's not part of the solution.

Thanks in advance for your help.
