Thanks to Nicolas, I've been able to create a cleaner solution: we track
some of the variables (ones for which we currently output something by
default, typically because they are set or because we choose to always
output something, like from-phone), and we only output the code if the
variable was set in the file. Thus if nothing is set, the lco file
wins. Note that with this approach, one can have a default in the lco
that is overridden by the file, for instance for foldmarks or to display
phone numbers.

Regarding the name and email, we output it before the lco if they are
not specified in the file, and after if they are.

What do you think of this approach? Are there other variables we should
track?

Best,

Alan
