From 3e125c0c017e346768f9882882c31b81cc07940f Mon Sep 17 00:00:00 2001 From: Brad King Date: Tue, 11 Sep 2018 14:04:33 -0400 Subject: Ninja,Makefile: Drop extra space after RULE_LAUNCH_CUSTOM value The Ninja and Makefile generators were adding a space to the value both before and after expanding rule variables. Only the latter is needed. While at it, revise some outdated comments since the rule variable expansion is no longer responsible for inserting the launcher.
