[PATCH 0/4] grep: retire `init_grep_defaults()`

Users of the grep machinery need to call `init_grep_defaults()` to populate some defaults. There's a comment: "We could let the compiler do this, but without C99 initializers the code gets unwieldy and unreadable, so...".

We have such initializers now, so we can simplify accordingly.

Martin Ågren (4):
  grep: don't set up a "default" repo for grep
  grep: use designated initializers for `grep_defaults`
  grep: simplify color setup
  MyFirstObjectWalk: drop `init_walken_defaults()`
