Indeed, it does not make sense, but I realized it only when I fully understood the behavior. If one experiments, customizing several variables in row, it will take time to identify the origin of the message. Specifying in the documentation of the Customize buffer (=customize docstring?) that the value of this variables has to be greater than or equal to 1 will certainly help; also having as the error message, instead of the current one, would be even better (perhaps that is what you call a "guard"). -- EOST (École et Observatoire des Sciences de la Terre) ITE (Institut Terre & Environnement) | alain.coch...@unistra.fr 5 rue René Descartes [bureau 110] | Phone: +33 (0)3 68 85 50 44 F-67084 Strasbourg Cedex, France | [ slot available for rent ]
