+If I'm not mistaken, the `--locked` and `--unlocked` limiting options
+are intended to work with `find --branch`, but that leads to empty
+output in all the cases I've tried.

+Lines 29-49 show the output I expected.  On the other hand, I thought
+the last two lines, which combine --branch with --locked and
+--unlocked, would show the same output as lines 35 and 37.
+
+I dug a bit hoping I could figure out what was going on, but I haven't
+had any luck so far.
+
+Thanks in advance.
