From 09afd4d8b287a7401451541a93343987db979db8 Mon Sep 17 00:00:00 2001 From: Adam Spiers Date: Tue, 29 Nov 2011 22:41:04 +0000 Subject: [PATCH] Add support for suffixing parameters with '_append', and corresponding docs. This allows the option of constructing parameter values accumulatively rather than overriding existing parameter values.
