Subject: [PATCH 2/3] setup_revisions(): swap if/else bodies to make the next step more readable

From: Junio C Hamano <[email-masked]>
Date: Sun, 12 Feb 2017 10:41:31 -0800

Swap the condition and bodies of an "if (A) do_A else do_B" in
setup_revisions() to "if (!A) do_B else do A", to make the change in
the the next step easier to read.  

No behaviour change is intended in this step.
