Details:

I myself - and others http://permalink.gmane.org/gmane.os.cygwin/126369 - have
experienced that gnuplot does not work anymore.

E.g. when I executed imshow() from octave the function failed to complete due
to the following coding error in __gnuplot_get_var__.m:


-- in octave /usr/share/octave/3.4.0/m/plot/__gnuplot_get_var__.m
     the line 
          str = strcat(str {:});     ---------latest version
          str = strcat(str, {:});    ---------previous version


The previous version is correct, which I have fixed manually.

After this imshow() still fails at this line in the same file:


## Strip out EOLs and the continuation character "|"
   141     str(str=="\n") = "";
   142     str(str=="\r") = "";


I have repleced this code with


## Strip out EOLs and the continuation character "|"
    str = strrep(str, "\n", "");
    str = strrep(str, "\r", "");


and now imshow() works for me again. I think these fixes should be
incorporated into the stable version. Thanks.
