Subject: Not removing and then re-adding the magic line when a Backspace happens
X-Git-Tag: v2.5.0~177
X-Git-Url: https://git.wh0rd.org/?a=commitdiff_plain;h=fc7825d00d62511cb8aa528f285b9a09f10ee608;p=nano.git

Not removing and then re-adding the magic line when a Backspace happens
at the end-of-file; just adding a token undo item to be able to put the
cursor back at the very tail of the file.
