C-X Tab is still undefined.
Rubbing out the last character of a line, when that eliminates
the need for a continuation line, does not get rid of it or
erase the char rubbed out.  I suspect the wrong criterion is being
used for what to mung.  I think that the same problem exists in the code
that inserts a character at the end of a line to make a continuation line,
but that has had no noticeable consequences until now, when it disables
somehow the insert/delete line processing I have just implemented.
