+So, we seem to have two cases, in one po files from the underlay should be
+used, in the other not. Hmm. Support both?

+Duplicate %links ?
+------------------
+
+I notice code in the scan hook that seems to assume
+that %links will accumulate duplicate links for a page.
+That used to be so, but the bug was fixed. Does this mean
+that po might be replacing the only link on a page, in error?
