    plug-ins: install Python plug-ins in rwxr-xr-x.
    
    Without the write permission for the owner, the `make install-plug-ins`
    special target fails on Python plug-ins. And anyway I don't see a reason
    why not give write permission to the owner (like all other plug-ins are
    installed).
