BTW, I said it's only used in "svn" but it's used a bit in one or more of the
accompanying programs "svnadmin", "svnserve", etc. as well.

Yes, that sounds right.

Create a new one. As it's local to the command-line client program(s) and not a
public thing exposed by libraries, ... oh, but it will be exposed by the public
svn_client_args_to_target_arrayN(). In that case, yes, like you said,
"svn_client_target_t" would be a good name.
Your struct will only have two of the fields that svn_client_copy_source_t has,
so doesn't replace it, so no point in changing the ...copy4() API. And I think
your struct might as well have the revision struct embedded in like
svn_wc_external_item2_t does, rather than another level of indirection like
..._copy_source_t uses, since it's small and constant-size.
