cannot specify a page to start with to go until the end

[as-muncher]

For instance, when prompted for a page #, I don't want to have to look up the exact number of total pages. I want to enter something like "356-" to denote starting at page 356 to the end. If the book only has 700 pages, and I enter a number greater than that, another error.
