[hts-users:03608] Re: dynamic window specification

["Heiga ZEN (Byung Ha CHUN)" <heigazen@xxxxxxxxxx>]

They are the same.  However, to avoid confusions, I recommend you to use

5 1.0 1.0 [-2.0] 1.0 0.0

for this case.

I personally think that it was my mistake to introduce the following code.

     if (fsize % 2 == 0)
         win->r_width[i]--;
