[Bug-wget] Compatibility

[Towle, Jonathan J.]

We are running various versions of wget on our servers.

On the server we need to use, we are running the very old version 1.9.1.    We 
could upgrade either to 1.11.4, which we have on most of our servers, or the 
latest version.

Our operate team is afraid to upgrade because existing production jobs are 
running 1.9.1.    I assured them that it is almost certain that the newer 
versions are backwards-compatible, and nothing will stop working.

Can someone confirm that all these versions are backwards-compatible?

Thanks in advance.

-Jonathan
