Urgh. assuming that we should not read .gitattributes if there's no
worktree to read from (similar to the "defaults to .git" situation),
how about

 - if mailmap stuff is requested, setup worktree, or die trying
 - if worktree is detected, but setup code does not jump to it, do it
 - if no worktree is detected, tell git-log to stop reading .gitattributes

We probablly want some "if no wotktree then die()" in .gitattributes
and .gitignore code, just in case it's incorrectly and accidentally
executed in exotic setup
