Okay, I've confirmed this, and as far as I've been able to determine you are correct. The problem only seems to be with the warning, not format itself.
In format-string-argument-count in the module module/language/tree-il/analyze.scm the ~! option gets picked up by the else case of the loop, which adds one to both the max and minimum number of parameters. Clearly this is a mistake. I'm currently looking through the format docs to see if any others are mishandled, and will post a patch later. PS. I'm really glad this wasn't a bug in format, since that is one scary function. :) -- Ian Price -- shift-reset.com "Programming is like pinball.
