[Gretl-devel] question-mark bug fixed

Today's snapshot (the same code as in the 2017c release) fixes a recently introduced bug that I found in regression-testing for the release. Namely, the new facility of using '?' as a wildcard (matching any single character) when defining a list had broken the use of the ternary operator "? :" in list definition. Now both uses of the question mark should be handled correctly. Allin
