The part of code that removed space at start of paragraph have been there forever, but its intent is unclear. For example, cutting text at the end of a paragraph will lead to remove space at the start of this same paragraph. The removal of this functionality is offset by a rewrite of DEPM that makes it more thorough. Fixes bug #10503.
