Wrap faces in erm-define-faces and attach with a hook
Indent continued postconditionals

This change treats lines with trailing post condition keywords (+ and or)
as continuation lines:

x = 3 if
    y

x = 3 unless
    y

x = 3 and
    y = 4

x = 3 or
    y = 4

trailing indents should be 2, not 1. duh.
