Bug in http module of guile-www

[Robert Marlow]

Hi all (I hope I'm posting this to the correct list. IIRC you guys also
handle guile-www)

I happened accross a bug in the HTTP module of guile-www which seemed to
trigger when I visited a page which gave no headers and just whitespace
in the body. In such a case the variable "second" of parse-status-line
gets bound to #f which messes up the later make-shared-substrings which
use it.

Admittedly I didn't really study the http module too much to figure out
what that procedure was meant to do or the exact nature of the fail, but
I did produce a quick fix which worked for my purposes. Whether it's
correct or not I have no idea. Anyway, it's simple enough for those who
would know such things to digest and decide:

139,140c139,144
<         (make-shared-substring statline (1+ first) second)
<         (make-shared-substring statline (1+ second)))))

>             (make-shared-substring statline (1+ first) second)
>             #f)
>         (if second
>             (make-shared-substring statline (1+ second))
>             #f))))


Apologies it's not in unified diff. The diff on this machine doesn't
seem to support it.
