It has nothing to do with Mercurial or Evolve, if you mean that.

The syntax `ENVVAR=value command` is common to most shells, as far as I
know. It starts a command with the given environment value set with that
value. Even the fish shell, which has a different syntax to assign
variables (`set var value`), accepts that syntax in those cases.

I didn't know that it's a deprecated environment variable in Mercurial. But the
standard ones can be used too:

........
VISUAL
    This is the name of the editor to use when committing. See EDITOR.

EDITOR
    Sometimes Mercurial needs to open a text file in an editor for a user
    to modify, for example when writing commit messages. The editor it
    uses is determined by looking at the environment variables HGEDITOR,
    VISUAL and EDITOR, in that order. The first non-empty one is chosen.
    If all of them are empty, the editor defaults to 'vi'.

Anyway in the Mercurial list
(https://lists.mercurial-scm.org/pipermail/mercurial/2023-April/106227.html)
Sietse Brouwer proposed an alternative solution with `config.ui.editor`.
