Just a proxy; calls cb__record_changes_mixed() with the root, target and pool, and default values for the rest.

		svn_revnum_t	target,
		char *	other_paths[],
		svn_revnum_t	other_revs,
		apr_pool_t *	pool
	)

-.

Like cb__record_changes(), but allowing mixed reporting.

Calls the svn libraries and records which entries would be changed on this update on current_url.

Parameters:

	root	The root entry of this wc tree
	target	The target revision. SVN_INVALID_REVNUM is not valid.
	other_paths	A NULL-terminated list of paths that are sent to the svn_ra_reporter2_t::set_path().
	other_revs	The revision to be sent for other_paths.
	pool	An APR-pool.

When a non-directory entry gets replaced by a directory, its MD5 is lost (because the directory is initialized to entry_count=0 , by_inode=by_name=NULL ); that should not matter, since we have modification flags in entry_status .

If a non-directory gets replaced by a directory, entry_count and by_inode are kept - we need them for up__rmdir() to remove known child entries.

Please note that it's not possible to run invisible entries (that are not seen because some higher priority URL overlays them) to run as baton==NULL (although that would save quite a bit of url__current_has_precedence() calls), because it's possible that some file in a directory below can be seen.

other_paths is a NULL -terminated list of pathnames (which may have the "./" in front, ie. the normalized paths) that are to be reported at revision other_revs.

If other_paths is NULL, or doesn't include an "." entry, the WC root is reported to be at current_url->current_rev or, if this is 0, to be at target, but empty.

int cb__remove_from_url	(	struct estat *	root,

-.

Removes all entries belonging to to_remove from the tree root.

While recursion we look for the highest priority URL in the children (within each level); if there is one, we mark the directory as belonging to that URL.

Will be easier with mixed-WC operation; currently it's not correct if there are overlayed non-directory entries.
