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.
