WEBrick::HTTPUtils::parse_query replaces plus (+) with space

ruby 2.0.0p0 (2013-02-24 revision 39474) [x86_64-darwin12.3.0]

[ruby-core:54601]

Description

According to RFC1738, the plus character (+) is a reserved character and may be used unencoded within a URL. Webrick however replaces plus signs with spaces, which violates the spec and causes a loss of information. An encoded plus character (%2B) is correctly decoded by Webrick.

This bug affects Ruby 1.8, 1.9 and 2.0.
