[PATCH 0/4] Drop git-exec-path from non-Git child programs

["D. Ben Knoble" <ben.knoble+github@gmail.com>]

This has caused trouble in the past [1] [2]; after attempting to help
Git-for-Windows avoid that problem in Vim [3] by recommendation [4], it
was suggested that upstreaming the change instead would be a better
solution. Indeed, this should work for more uses/editors/etc.

I haven't managed to test this on Windows, so any extra eyeballs there
are greatly appreciated. I'd also appreciate suggestions to fix the
memory leak.

Structure: patches 1 & 2 are cleanups. In particular, patch 1 is essential to
the tests in patch 4. I don't think patch 2 is strictly needed. Patch 3
refactors a little to make patch 4 take effect on all platforms. Patch 4 does
the real work.

D. Ben Knoble (4):
  t7005: sanitize test environment for subsequent tests
  editor: use standard strvec API to receive environment for external
    editors
  run-command: prep_childenv on all platforms
  drop git_exec_path() from non-Git commands' PATH
