Yuck, what an ugly hack when you are so close.  Why not restructure the
code in such a way that the updated config-set-multivar and set-in-file
share the code better?  If the former takes a hardcoded logic to decide
which file to write to while the latter takes the filename to write to as
its argument, wouldn't it be a lot more natural to make config-set-multivar
call set-in-file after computing what filename parameter to pass?
