+Subject: [PATCH] autogen.sh: drop '-unknown' suffix from version number
+
+If autogen.sh is run outside of a git repo, the find-version function
+always assumes that libassuan is a beta version and adds the suffix
+'-unknown' to the version number. This should not work for users who use
+tarball and re-run autoconf in build directory.
+
+Upstream-Status: Inappropriate [oe specific]
