[PATCH 0/2] here-doc test bodies

This is a re-post of an idea from 2021:

  https://lore.kernel.org/git/YHDUg6ZR5vu93kGm@coredump.intra.peff.net/

that people seemed mostly positive on, and I just never got around to following up. Mostly because it's not life-changing, but I think it is a small quality of life improvement, and it came up again recently in:

  https://lore.kernel.org/git/20240701032047.GA610406@coredump.intra.peff.net/

So I thought it was worth considering again.

  [1/2]: test-lib: allow test snippets as here-docs
  [2/2]: t: convert some here-doc test bodies
