Details:

Using Octave-3.8.1 from standard Ubuntu 14.04 repositories (64-bit OS)

I have found some weird behavior of num2str function. Sometimes it produces
additional blank line.

c = [
  -0.00000   0.71500  -0.00000
  -0.00000  -0.71500   0.00000
   1.23760  -1.40040   0.00000
  -1.23760  -1.40040   0.00000
];

% Produces additional blank line
num2str(c,'%3.8f %3.8f %3.8f \n')

% Also produces additional blank line
num2str(c(1:3,:),'%3.8f %3.8f %3.8f \n')

% However, this does not produce the blank line
num2str(c(3:4,:),'%3.8f %3.8f %3.8f \n')

When I use larger matrix (more rows), the problem repeats after every 3 lines
- it is probably some general problem, independent on what exactly is on the
3rd line...

Also affects Octave 3.8.2, Matlab doesn't have this problem
