bug#22553: 24.5; enriched-mode: Formatting changes immediately before <RET> are lost

[Travis Evans]

While typing text in Enriched Text mode, if a face property is changed
but RET immediately follows, the change is not applied to the
subsequently entered text.

From ‘emacs -Q’:
C-x b newbuffer M-x enriched-mode M-o u Test M-o d <RET>

Text typed after this should no longer be underlined, but it is. The
underlining does stop if C-j is used in place of RET, but it doesn't
seem that this would be very intuitive for a new user.
