Details:

File imp3.txt:

1 11
 22
3 33

(no trailing spaces after 2nd column)

Octave:

>> dlmread ('imp3.txt', ' ')
ans =

    1   11
   22    0
    3   33

>> dlmread ('imp3.txt')
ans =

    1   11
   22    0
    3   33


ML r2012a gives for first call (correctly, I think):

1   11
0   22
3   33

and for the second (w/o specified delimiter)

 1   11
22    0
 3   33

so Octave is ML-compatible in the second case.

(FYI, I've seen bug #32260. That is about dlm behavior for leading whitespace
when no delimiter is specified)
