Fix #26 Issues with 'truncate-lines nil (Wrap at window edge)

[arximboldi]

I'm having trouble on GNU Emacs 25.1.1:

fci-mode: Wrong type argument: number-or-marker-p, nil

Full stack trace:

I've resolved this conflict and pushed here:

https://github.com/alpaker/Fill-Column-Indicator/compare/master...aspiers:wrap-window-edge

However I have no idea if it's the right approach. It still doesn't work well for me.
