+Subject: [PATCH] core: fix libgit ifdef to handle libgit2 v1.0 and onwards
+
+Conditional code for older libgit versions was removed in
+https://github.com/Subsurface-divelog/subsurface/pull/2737,
+but it's a non-trivial backport, and master currently isn't really ready
+for a release.
+
+So instead ship a patch fixing the one broken libgit2 conditional until
+a 4.10 release has been made.
+
+Note the inverted logic - the if branch now handles the old libgit
+condition, and the else branch the newer versions, consistent with how
+it's done in the rest of the subsurface codebase.
