change to "enter" (CR) in LIsts

Under today's change, the invisible character of "enter" or Carriage Return is handled differently than before in both the List's description and descriptions added to titles.

On this list

the URLs used to start on their own line, both in the List description and the title descriptions.

Also, in the List description, the green text each used to start on their own line too.

When I try to fix it by introducing another "enter", I get double spacing instead of single, as you can see on this list:

In addition to preventing me from defining where a line begins and having single-spaced separate lines, this has made the edit mode non-WYSIWIG.
