fastannotate: use repo.local() This is the proper way to check whether we're dealing with a local repository, since extensions should be coding to an interface and not testing for exact types. Differential Revision: https://phab.mercurial-scm.org/D4542

tests: drop extra "file:" prefix from paths in narrow test It looks like these were added by mistake in f4d4bd8c8911 (narrow: add a --narrowspec flag to clone command, 2018-08-08). Differential Revision: https://phab.mercurial-scm.org/D4531

narrow: validate spec files are well-formed during clone (BC) Previously, specfiles would get read then normalized. We want specfiles to be normalized on read so there is no confusion about what the format of specfiles should be. This commit validates the parsed result of --specfile. If entries aren't prefixed, an error is raised. Previously, validation would occur at exchange time, hence why we dropped a line of test output related to server iteraction.
