I don't follow what you're saying here.  Undo should not change
something and keep it out of view (unless of course the changed
region is so large that it doesn't fit entirely on the screen).

One other thing:

+           statusbar(action == COMMENT ? _("The line is not commentable") :
+                                       _("The line is not uncommentable"));

How can a line not be commentable?  Isn't this case already handled
by the 'if (strlen(comment_seq) == 0)' above?  Or is this just for
the magic line?

Testing...  Run 'src/nano --ignore --nonew +99 README', then type:
M-3  M-U

Segmentation fault.
