possible bug/addition to wget

[bob stephens [contr]]

Hi WGet folks,

This isnt really a bug I found in the operation of wget, but I think  
it is a functionality problem.

I wonder if you can help me. I would like to use wget to mirror an  
ftp site - this step seems easy.
BUT, I would like to set it up so that the files on my end are un- 
gzipped. When I did this step, of course it goes and looks for the  
gzipped file, doesnt find it and then goes ahead and redownloads the  
file. Is there a way to make it smart enough to see that the file  
exists in an alternate form.
I can fix it if you can give me a clue as to where to look in the  
code - in the compare files section of ftp.c it looks like it does  
the comparison using strcmp - but maybe it could be changed to say  
"if the file has the extension gz (or Z or zip), then look for the  
file without the extension too.

Does this sound dooable - it seems to me like it would be a useful  
modification. I was hoping I wouldnt have to get the .listing file  
and make the modifications in there.
Thanks alot,

Bob
