Sorry for the answer delay.
I confirm that I have tried to make line numbering   deal with physical
line numbers in all cases.

In the exemple you mentioned, the execution is not stopped in the middle
of line 6, The logical line formed by line 6 and 7 is supposed to be in
the line 7 while line 6 is supposed to be empty.

The function foo below
function foo
  a=1
  disp(a),..
  disp('ok')
endfunction
is then equivalent to
function foo
  a=1
 
  disp(a),disp('ok')
endfunction

This is done this way because continuation marks can be put anywhere
even inside an expression ans in the silly example below
function foo
y..
=sin(..
1+..
2..
)
endfunction
