'tail' endpoint closer to the bottom. That makes more sense.

Consecutive additions all happen on the same line. When automatic

item, and subsequent additions go into a new ADD item.

rcfile: do not allow a regex for name, header, or magic to be empty
...
If the user really wants to match anything, ".*" should be used.
(This also stops nano looking at the rest of the line as soon as an
empty regular expression is encountered. This may seem like poorer
feedback than before, but... I think that multiple error messages
per line are more confusing than helpful.)

Reshuffle it to the beginning also because it is used the most often.

files: when piping, always pipe whatever was cut to the external command

Either the marked region was cut (even when zero characters) or
the entire contents of the buffer were cut. In both cases this
is what needs to be piped to the command. That is: the contents
of the cutbuffer.
