From 4982516451ed4979bc7fc1a7f002fc310b060118 Mon Sep 17 00:00:00 2001 From: Denton Liu Date: Tue, 19 Nov 2019 16:51:13 -0800 Subject: [PATCH] revision: make get_revision_mark() return const pointer get_revision_mark() used to return a `char *`, even though all of the strings it was returning were string literals. Make get_revision_mark() return a `const char *` so that callers won't be tempted to modify the returned string.
