Merge branch 'jk/alias-in-bare'

Browse Source 
An aliased command spawned from a bare repository that does not say
it is bare with "core.bare = yes" is treated as non-bare by mistake.

* jk/alias-in-bare:
  setup: suppress implicit "." work-tree for bare repos
  environment: add GIT_PREFIX to local_repo_env
  cache.h: drop LOCAL_REPO_ENV_SIZE
