Bug #8898: NET::HTTP always raises an exception if http_proxy="" (empty string)

ruby -v: ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux]
Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN


The new URI::Generic.find_proxy code uses this environment variable, even if it's set to "". I believe it should test if it's "", and behave as if there was no proxy (nil if "").
Previous rubies behave as expected, ignoring http_proxy="" (only tested 1.9.3, 1.9.2 and ree-1.8.7)

http_proxy="" rvm use ruby 2.0.0 exec ruby -e 'require "net/http"; p Net::HTTP::Proxy(nil, nil).new("www.google.com", 80).get("/")'
