Yes, this is probably cleaner than my workaround with "none".
But it needs one extra boolean field, and the "none" solution should be
safe too.
(Afaik there is no system where "none" without slashes is a valid
absolute path).
I typically use '<none>' to signal invalid entries, easily recognizable
by the first character. A non-visual solution were e.g. a #0, that
should be an illegal value in most cases, but still is a non-empty string.
