I think that in our use case, program-file is better, because it does
not require to call Guile explicitly in the Sway configuration (all we
care about is that the serialised script "behaves like a menu program").

Yes, this is arbitrary in my code.  Rationale behind my choice:

At first, I wanted to make the default value match that of the default
Sway configuration file.  However, this would force some fields to be
mandatory (namely status-command, colors and position).  As users may
not want to specify these fields in their Sway configuration,
I preferred to make everything optional.

I first tried to use (open-pipe wmenu OPEN_BOTH).  However, I needed
to close the port to wmenu before reading its output.  I do not know how
to do that with `open-pipe'.
