reading the code for the version of portage I have installed: |

The NewsManager will call Isvalid on each news item and each news item |
| 19 |
will scan its restrictions for 'valid-ness' and report that upward. So |

if we are lucky, on old versions of portage, portage.isvalidatom will |
| 21 |
report the USE-dep as an invalid atom and portage will print mean |

errors messages about 'invalid news items' but will not throw up (in |
| 23 |
theory). |
