[Bug-wget] Wget no_proxy parsing issue

[Timothy Rafael Cardenas2]

This is a minor issue with the wget no_proxy env var parsing. If a 
trailing comma is left on the string containing all addresses not to be 
used with the proxy server then wget simply reports back with timeout 
errors. Adding a trailing comma is a common practice in ubuntu and to 
ensure that this issue does happen again i would imagine a better error 
message or just a small special case added to the parsing routine of wgets 
env vars.
