I now understand: I have "addversionno = true" in my config file. This is useful when unison is built from the tar.gz (e.g. when the target machine is not a Debian one). But this is buggy on Debian. Since this option adds "2.13" only (not "2.13.16"), then the Debian package should probably provide a symbolic link:
