>
> The following if a valid diff command: "diff -y -W 200 /tmp/b1 /tmp/b2".
> But when passed to zdiff the space between "-W" and 200 causes the
> COLUMNS argument to be interpreted as a file:
> zdiff -y -W 200 /tmp/b1 /tmp/b2
> /bin/zdiff: 72: /bin/zdiff: cannot open 200: No such file
>
> The error is caused by the following line in the loop that processes
> the arguments:
> -?*) cmp="$cmp '$1'";; (line 63 in version  1.6)
>
> There should be an additional check to catch options with arguments. I
> couldn't come up with a working solution quickly so I am currently
> using a workaround.
> If I remove the space between the option "-W" and it's COLUMNS
> argument the script works as expected.

> With this workaround the zdiff utility is great solution for the
> problem I'm working on, thanks!
