In Text mode typing RET on a formfeed character ^L deletes it.
The presence of ^L means it's here on purpose, so RET should keep it.
electric-indent-post-self-insert-function calls indent-according-to-mode
that uses special casing for indent-relative (that is the default
indent-line-function in text-mode). I don't understand why it
calls ^L-eating indent-line-to instead of indent-relative
but without this special casing, indent-relative works fine
and doesn't eat ^L.

If we can get the same behavior using indent-relative, I'm perfectly
fine with it. But I also think that indent-line-to should *not* eat ^L.

This patch fixes the problem and doesn't eat ^L:
