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).
