The discussion that led to the naming of that LEGACY token needs to be
re-read, then. The kind of "LEGACY" you prefer is exactly why the
environment variable is called LEGACY in the patch you are commenting on,
written in response to Linus's suggestion to switch the default, even
though I am not 100% buying it.

Having said that, I think I am wasting my time responding to this thread
during the feature-freeze period for v1.7.9, as I am not a big fan of
switching the default without adequate warning and transition plans, after
getting burned by the "'git-foo' vs 'git foo'" flames back in the v1.6.0
release. We would likely to take a gradual and smoother migration route to
transition, e.g. v1.7.9 to introduce "merge --edit", v1.7.10 to introduce
a configuration variable merge.edit (lack of which gives a warning and an
advice message while defaulting to 'no' to preserve the traditional
behaviour), and finally v1.8.0 (or v2.0) to flip the default to 'yes'
(while the configuration still giving a warning and an advice message)
that "merge --no-edit" can still countermand.

So you have until v1.7.10 to decide a good name for the overriding
environment variable.
