Details:


textscan('/home/foo/','%s','delimiter','/','MultipleDelimsAsOne',1)


This command returns {'home'} instead of {'home','foo'}. The correct output is
returned when the trailing delimiter is removed: '/home/foo'.

I could track down the problem in strread>split_by:


## In case of trailing delimiter, strip stray last empty word
  if (! isempty (out) && any (sep == text(end)))
    out(end) = [];
  endif


but I am not sure of what the right fix would be without breaking other
situations.
