Hi. For variables of type string, is there any difference between empty and unset? I am trying to add a feature dependent on a new string option (call it opt_foo), and I contrived to do different things when the C variable corresponding to the option is NULL, vs. when it points to the empty string. But when I run my patched binary and I do
:set opt_foo="" I get the behavior for NULL :-( This makes me think mutt cannot separate these two cases, and I have to use some special non-empty value instead. Is this right? -- Please *no* private copies of mailing list or newsgroup messages. Rule 420: All persons more than eight miles high to leave the court.
