In standard linux parlance, "hidden" usually means that the file name starts with ".", and nothing else. Rename the function to convey what the function does better to casual readers. Stop exposing hidden_file_allow_backup which is rather ugly and rewrite hidden_file to extract the suffix first. Note that hidden_file_allow_backup excluded files with "~" at the end, which is quite confusing. Let's get rid of it before it gets used in the wrong place.
