[Chicken-hackers] [PATCH] Fix bad call in chicken-install error situation

[Peter Bex]

Hi all,

I had some networking trouble just now and noticed that chicken-install
showed the following output, which is obviously incorrect:

TCP connect timeout

Error: bad argument count - received 2 but expected 3: #<procedure>

A similar situation can easily be triggered by calling chicken-install
with a nonexistent hostname:

$ chicken-install -l foo bar
retrieving ...
connecting to host "foo", port 80 ...
TCP connect timeout

Error: bad argument count - received 2 but expected 3: #<procedure>

The attached patch fixes the immediate error by calling "proc" with
three arguments instead of two.  However, I'm still a little unsure
how this is supposed to work.  For example, in
list-available-extensions, if "trans" is false, it will invoke the
NEXT procedure, which is #f.  I've tried but was unable to trigger
an error situation, so I suppose it's okay the way it is (but I still
don't understand).

Cheers,
Peter
