It is easy to add incorrect "linkgit:<page>[<section>]" references to our documentation suite. Catch these common classes of errors: * Referring to Documentation/<page>.txt that does not exist. * Referring to a <page> outside the Git suite. In general, <page> must begin with "git". * Listing the manual <section> incorrectly. The first line of the Documentation/<page>.txt must end with "(<section>)". with a new script "ci/lint-gitlink", and drive it from "make check-docs". Signed-off-by: Junio C Hamano <gitster@pobox.com>
