man: change license of examples to MIT-0 Quoting Richard Fontana in [1]: CC0 has been listed by Fedora as a 'good' license for code and content (corresponding to allowed and allowed-content under the new system). We plan to classify CC0 as allowed-content only, so that CC0 would no longer be allowed for code. Over a long period of time a consensus has been building in FOSS that licenses that preclude any form of patent licensing or patent forbearance cannot be considered FOSS. CC0 has a clause that says: "No trademark or patent rights held by Affirmer are waived, abandoned, surrendered, licensed or otherwise affected by this document." (The trademark side of that clause is nonproblematic from a FOSS licensing norms standpoint.) The regular Creative Commons licenses have similar clauses. For the case of our documentation snippets, patent issues do not matter much. But it is always nicer to have a license that is considerred acceptable without any further considerations. So let's change the license to the (now recommended replacement) MIT-0.
