OK, you're saying keep svn_wc_conflicted_p2() but change its
tree_conflict output to report on the path as a victim:
path, entry, pool);

Yes. Each part of the up/sw/merge operation is trying to say:
if target was already in conflict:
skip this action
if this action will cause a tree conflict:
record the tree conflict
skip this action
do this action

check_tree_conflict() doesn't detect pre-existing conflict, it only
detects whether the current action is causing a conflict, so yes we need
it and also (logically before it) a check for pre-existing conflicts.
But Steve's point was that to check for pre-existing conflicts we have
the API svn_wc_get_tree_conflict() to ask if a path is the victim of a
tree conflict. We can use svn_wc_get_tree_conflict() together with
svn_wc_conflicted_p() to answer the same question as your proposed
svn_wc_conflicted_p2() will do.
When svn_wc_conflicted_p2() was ansering "does this path have any
tree-conflicted children", I thought it was better to separate out that
question into a separate API, but now that we can answer all three of
* is there a text conflict on this path?
* is there a property conflict on this path?
* is there a tree conflict on this path?
with one svn_wc_conflicted_p2() API, it seems neat and useful to do so.
I'm not entirely convinced it's the most useful API in the world: most
callers of it simply want to know whether there are any conflicts on the
path, and don't care what they are. But it's OK. Go for it. (First step:
stop using the current svn_wc_conflicted_p2()'s
