   3 # Description: Clean filename or dirname (either hovered or selections)
   4 #              to be more shell-friendly. This script cleans
   5 #              non A-Za-z0-9._- characters.
   6 #              and replaces it with underscore (_).
   7 #
   8 #              It supports cleaning single/double quote, newline,
   9 #              leading, trailing spaces.
  10 #
  11 #              eg.
  12 #              to be continued (つづく).mp4  -> to_be_continued______.mp4
  13 #              [work] stuff.txt              -> _work__stuff.txt
  14 #              home's server                 -> home_s_server
  15 #                qwe\trty                    -> __qwe_rty
  16 #
  17 #              And if there are two almost similar filenames
  18 #              like: 'asd]f' and 'asd f' both will be renamed to 'asd_f',
  19 #              to avoid overwriting, the last file will be prepended by _.
  20 #              So they will be: 'asd_f' and '_asd_f'
