Command to force to delete all trailing spaces

[bachue]

Now I set "trailing_spaces_modified_lines_only" to true in the configuration, this feature is really useful to me. But sometimes I really need to delete all trailing spaces in the whole file, not only modified lines, but after I use command to delete trailing spaces, some spaces are not removed. So I guess the problem is "trailing_spaces_modified_lines_only". Is there any way that I can force to delete trailing spaces in the whole file? Thanks.
