[PATCH v2 0/4] grep: simplify "grep defaults" handling

This is v2 of my series [1] to simplify the setup and use of the `struct grep_opt grep_defaults`. The only difference compared to v1 is in the third patch which now drops more code in favor of copying the whole struct in one go.

Martin Ågren (4):
  grep: don't set up a "default" repo for grep
  grep: use designated initializers for `grep_defaults`
  grep: copy struct in one fell swoop
  MyFirstObjectWalk: drop `init_walken_defaults()`
