I have only two wgetrc related files as follows:

/etc/wgetrc
/usr/doc/wget-1.8.2/sample.wgetrc

NB: I use win98 and these are under my cygwin directory i:\cygwin (i.e. 
/cygdrive/i).

I have never changed either file--I just accept the default installed by 
setup.  However, the two files differ by a few lines which are just 
comments anyway. i.e. doing:

$ diff /etc/wgetrc /usr/doc/wget-1.8.2/sample.wgetrc
73,74c73,74

shows this.  Moreover,

$ grep robot /etc/wgetrc
# Setting this to off makes Wget not download /robots.txt.  Be sure to
# know *exactly* what /robots.txt is and how it is used before changing
#robots = on

shows the only references to "robot" are also comments.

The stated default for wget is "robots=on" which I have seen honored for 
quite a number of other downloads and since I didn't use "-e 
robots=off", that can't explain it.  The only other thing I have found 
that might be related is not under my control and I haven't yet figured 
out how to check it.  From the wget documentation it states:

"
The second, less known mechanism, enables the author of an individual 
document to specify whether they want the links from the file to be 
followed by a robot. This is achieved using the META tag, like this:

<meta name="robots" content="nofollow">

This is explained in some detail at 
<http://www.robotstxt.org/wc/meta-user.html>. Wget supports this method 
of robot exclusion in addition to the usual /robots.txt exclusion.
"

Perhaps there is a counterpart to the above, i.e., <meta name="robots" 
content="follow"> that's being involked and someone from Redhat could 
check into and rule this out.

Thanks (and still puzzled)!
