+commit 5e0f3e6298bde0c6e44bd4db956a7287f9ff3f88

+
+    Turn invalid double separator error into a warning
+    
+    - As hysterical as it seems, people keep banging their heads into this:
+      older distros have these invalid dependencies deployed etc and people
+      do expect to create srpms and do test-builds on newer distros they're
+      running themselves. Which, put that way, seems rather reasonable...
+    - For history reference, the sanity check was originally introduced in
+      commit b2cf1471bbe2c35e3c36510a9e3f59919d8ed2c8 and
+      67ccf8d99630f4edad0ea16dddaca0a3355fba00,
+    - Backported from commit 1b3f7547c532b1f5ad68228571f1716d5be5b455
