See bail_on_tree_conflicted_ancestor() in libsvn_client/commit_util.c.
That seems to do almost what you might need. It might be too strict,
however, because it looks for a top-most working copy root which is
not inside any other working copy. But you should allow commits from
multiple working copies even if the working copies are nested.

I'd suggest to look at *all* callers of svn_wc_is_wc_root().
If you cannot find any function that calls svn_wc_is_wc_root() and
does what you want, then you will probably have to implement a new
function, called for example svn_wc__find_wc_root().
You could use bail_on_tree_conflicted_ancestor() as an example of how
to walk upwards towards a working copy root. You could then send a patch
which adds just your new function.
