[Bug-wget] [PATCH] Print expected total download size in spider mode

[Rohit]

Hi,

This patch displays the expected total download size of files when called with 
--spider. Its quite useful if you have a list of links (eg: wget --spider -i 
<file>) to be dowloaded and would like to know the total size. Please let me 
know of any changes/comments etc.  

Thanks,
Rohit
