This looks good to me.

If you search the source for translator: you'll find lots of examples. 
Here's one that was pretty relevant:

/* translator: %s is a configuration file */

We could probably phrase that as:

/* translator: %s is a backup_label or pg_control file */

That note goes right above the hint, so something like:

+                                /* translator: %s is a backup_label or 
pg_control file */
+                 errdetail("Latest checkpoint in %s is at %X/%X on timeline %u, but 
in the history of the requested timeline, the server forked off from 
that timeline at %X/%X.",
+                           haveBackupLabel ? "backup_label" : "pg_control",
