Infer a --repository argument from command arguments when reasonable. In particular: if invoked without -R from a CWD not inside a repo, having been passed one or more file paths as command arguments, where the nearest enclosing repo of all of those paths is the same, quietly infer a -R option for that repo. Otherwise abort with an error message as before.
