We need the code change otherwise it will fail at a
later stage(after signaling marking the tree-conflict). Then the
obstructed db->path would be disturbed unnecessarily.

With this update_editor.c change following is the status of WC.
/home/kamesh/tree_conflicts/bin/svn st

Without update_editor.c change
/home/kamesh/tree_conflicts/bin/svn st
svn-test-work/working_copies/checkout_tests-7.other/
! svn-test-work/working_copies/checkout_tests-7.other
    S svn-test-work/working_copies/checkout_tests-7.other/A

Why 'svn-test-work/working_copies/checkout_tests-7.other/A' should be
left in a locked state?

svn: Invalid tree conflict data

Why 'svn-test-work/working_copies/checkout_tests-7.other' should have
incomplete tree conflict data?

Ok. Will use that.

Ok. Will fix the comment. Blind copy paste :).

Find the attached patch with above 2 corrections.

Thanks for the review.
