another bug in selection_state()

Sure seems like I tested this and it worked but I guess I focused on
view_queue() and list_packages() at the wrong time. I knew
remove_files() (via view_cache_dir()) had a quoted list since source
names can include any kind of lunacy, unlike package names, but forgot
to allow for it. So allow zero or more dquotes around LINE.
