Details:

While thinking about the textscan()/strread() bugs in the tracker, it occurred
to me that the Matlab variants may rely heavily on regexp.  To check I ran a
test on how Matlab's textscan() handles "endofline" characters.

It appears that Matlab's default value for "endofline" is '\r\n|\n\r|\r|\n'.


a = textscan (sprintf ('A\r\nB\n\rC\rD\nE'), '%s')
a = {5x1 cell}
a{:}
ans = 
    'A'
    'B'
    'C'
    'D'
    'E'


My tip is;


changeset:   15866:c1c6502fe52b

summary:     oct-rand.cc: Silence compiler warning about possible
uninitialized variable.


And with the tip above, the default branch gives me 


a = textscan (sprintf ('A\r\nB\n\rC\rD\nE'), '%s')
a = 
{
  [1,1] = 
  {
    [1,1] = A
    [2,1] = B
D   [3,1] = C
    [4,1] = E
  }
}


Which implies the Octave implementation does not recognize "\r" as an
"endofline" character.
