Properly handle errors when following a symlink Fixes #123. The code assumes that every File that has its link_target() method called would first have been checked to make sure it’s actually a link first. Unfortunately it also assumed that the only thing that can go wrong while following a link is if the file wasn’t a link, meaning it crashes when given a link it doesn’t have permission to follow. This makes the file_target() method able to return either a file or path for displaying, as before, but also an IO error for when things go wrong. 2016-10-29 19:27:23 +00:00				`[36ml[1;33mr[31mw[32mx[0m[33mr[31mw[32mx[33mr[31mw[32mx[0m [1;32m0[0m root [34m29 Oct 17:23[0m [36m/proc/1/root[0m`
