Subject: Use `git var GIT_EDITOR` to call editor
X-Git-Url: https://git.phdru.name/?a=commitdiff_plain;ds=sidebyside;h=472be778aa9f5725f3a7757baa5c791b32182f2c;hp=472be778aa9f5725f3a7757baa5c791b32182f2c;p=git-scripts.git

Use `git var GIT_EDITOR` to call editor

`git var GIT_EDITOR` is better than ${VISUAL:-${EDITOR:-vi}} because
it takes into account all variables: GIT_EDITOR, VISUAL and EDITOR,
and falls back to the platform's default.
