Fixing whitespace characters problems

This is the result of running `whiter lib script t tools xt`.
Script `whiter` is the part of Test::Whitespaces module.

Here are the rules that this script uses:

 * Each line ends with "\n" (including the last line)
 * For new lines "\n" is used (not "\r\n")
 * There are no ending spaces on the lines
 * 4 spaces are used instead of tabs
 * No empty lines in the end of file
