From 2d14d65ce7b136b0fb18dcf27e5caff67829f658 Mon Sep 17 00:00:00 2001 From: Daniel Barkalow Date: Thu, 3 Sep 2009 22:13:51 -0400 Subject: [PATCH] Use a clearer style to issue commands to remote helpers This style is overkill for some commands, but it's worthwhile to use the same style to issue all commands, and it's useful to avoid open-coding string lengths.
