[PATCH 0/3] Implicitly use --no-index if git grep is used outside of repo

Often when looking for something in a downloaded source archive I find myself using git grep --no-index after forgetting to use --no-index the first time and git unhelpfully dies.

This patch series makes git grep implicitly run git grep --no-index when run outside of a repository, analogous to how git diff works when run outside of a repository.

Thomas Gummerer (3):
  t7810: correct --no-index test
  builtin/grep: rename use_index to no_index
  builtin/grep: allow implicit --no-index
