apply: a bit more comments on PATH_TO_BE_DELETED

The code is littered with to_be_deleted() whose purpose is not so clear.
Describe where it matters.  Also remove an extra space before "#define"
that snuck in by mistake at 7fac0ee (builtin-apply: keep information about
files to be deleted, 2009-04-11).

* PATH_TO_BE_DELETED for a path that a later patch would remove.

* The latter is needed to deal with a case where two paths A and B

* moving A to B should not be prevented due to presense of B as we
