But if you can do that for file-notify-supported-p, presumably you can
also arrange for file-notify-add-watch to fail in those cases.
I agree with Davis that in general it's better to run
file-notify-add-watch and handle any error it might signal, than to
use a function like file-notify-supported-p.
The only case where file-notify-supported-p makes sense is when you want
to know if file-notify-add-watch would work before you know whether you
want to call file-notify-add-watch. Can't think of too many situations
where this would be the case.
