    _______________________________________________________

Details:

Line 113 in usr/share/octave/3.6.2/m/io/textscan.m probably needs a !
inserted.

That is, 

    if ((isempty (args{ipos+1}) &&  has_str_fmt))

should probably be changed to

    if (! (isempty (args{ipos+1}) &&  has_str_fmt))


This fix worked in the MATLAB code I ported over and it makes the code
consistent with the comments.  I also noticed there were no test cases for
'whitespace'.

Thanks
