Perhaps I don't understand the difference. I thought that mode-line-format required that I specify the entire mode line from scratch, while I'm just proposing that if a particular function is bound that %p would override its method of calculating this one value. Am I mistaken on the former matter? -- Perry E. Metzger perry@piermont.com
