[ruby-core:30961] [Feature #3506] Kernel::URI with optional parser

Feature #3506: Kernel::URI with optional parser
http://redmine.ruby-lang.org/issues/show/3506

Author: Marc-Andre Lafortune
Status: Open, Priority: Low
Assigned to: akira yamada, Category: lib, Target version: 1.9.x

Kernel::URI could accept an optional parameter to specify a parser.

It could then be used in a couple of places in the library itself.

Patch follows:
