Ensure list_display works on outputs of unknown width
If getcols() returns 0, we were getting stuck before in a loop of no return. Teach getcols() to take a default value to return if the width is unknown, and use this everywhere as appropriate. Also make a few other cleanups while diagnosing this issue, such as const-ifying some variables. Noticed-by: Dave Reisner <d@falconindy.com> Signed-off-by: Dan McGee <dan@archlinux.org>
