I didn't look at more than mailx, but the description there makes it clear
that $EDITOR needs to expand to a command name. `more' has similar wording
("The name of the editor shall be taken from the environment variable
EDITOR.") and talks about what to do if the last pathname component in
$EDITOR is `vi' or `ex'.

As I said in a different message, historical convention is that these are
command names.
