+Subject: [PATCH] Use explicit default branch in %autosetup -S git
+
+Commit 3a6b1d8fbf846d3f1b139d343fdfddebe99ae42b assumed "master" as the
+default git branch to track, however the name can be changed globally,
+so make it explicit.
+
+Given the choice now, go with "main" as the general trend, e.g:
