[dw-free] Comment "Don't autoformat" option cannot be removed upon edit

[fu]

[commit: http://hg.dwscoalition.org/dw-free/rev/0a44f7843dbc]

http://bugs.dwscoalition.org/show_bug.cgi?id=4167

Instead of deleting from the hash, set to undef, so that set_props is still
aware that it needs to process these (and delete them from the DB if they
exist)
