[PATCH v4 0/3] clean up some code around editors

Changes from v3:
- drop 4/4
- use test_env (including a case our lint does not catch when the value
  has spaces)

Changes from v2:
- shuffle setup code and use more helpers in 1/4
- insert 2/4 to stop abusing --exec-path
- improve environment-cleansing idioms in {2 => 3}/4

Thanks especially to Phillip's encyclopaedic knowledge of test helpers ;)

Changes from v1:
- add a prep patch with style fixes to t7005
- rework the environment munging to use subshells, per Phillip Wood's
  suggestion

This reroll of the previous exec-path series is simplified to contain only the first 2 cleanup patches, which were largely acked by the list. Drop the controversial and broken PATH munging.

Also, this version is (still) based on a later master 112648dd6b (Merge branch 'master' of https://github.com/j6t/git-gui, 2025-08-04) than the original from May.

These patches clean up some old code in the editor tests and subsystem that does not use our modern idioms.
