Of course, as will asking them to save the file with a .R extension. The
main issue here is that there is a useful feature of ESS that is not
documented in a way that is clear to me: calling R-mode. This is the
simplest solution to my problem, uses an existing feature of ESS, and
only became an issue because it wasn't documented in a straightforward way.
