The rebirth arm of import-fossil required a zit store, so the verb that says 'import a fossil' could not take one. It now accepts the fossil's sync URL like --compatible does, cloning a transient flat store beside DIR and removing it after; a local store stays accepted. The zit->zit conversion gets its proper home as 'zit submanifest convert SRC DEST', beside 'enable', which now says what it does not do: existing check-ins stay flat, and fossil peers receive nothing new from the next commit. Diagnostics carry the verb the operator typed. Closes zit#168. check-in: abd850dc4c user: dmestas tags: trunk
