A) We should align the comment with the case statements.
B) We shouldn't have a gap of 4 characters between the start of comment and the
actual text.
C) I much prefer some English comment that explained what was removed + the
value (it's a nit as we are very inconsistent in this file).

A&B: Disagrees with how emacs indents by default, but sure, it looked silly. :)
Done.

C: Done. We ought to go through all the removed properties in that file and come
up with some kind of common style.
