launch_editor(): Heed GIT_EDITOR and core.editor settings

Browse Source 
In the commit 'Add GIT_EDITOR environment and core.editor
configuration variables', this was done for the shell scripts.
Port it over to builtin-tag's version of launch_editor(), which
is just about to be refactored into editor.c.
