So here's a suggestion: when we determine that a certain column of a
CSV file represents a string-valued variable, by default we treat
all non-blank values as string literals. But we provide a "set"
variable ("missing_string" or some such) so that the user can
specify a missing-code for string-valued input. E.g. when reading
from Alfred's tab-separated files one could say
set missing_string "."
(This would not just be for "join", but for any delimited-text
read.)
We already have "set csv_na"; we could use that.
