Subject: clean files of trailing whitespace

  Trailing whitespace is so unnecessary, that its presence may be removed
before files containing it are distributed.

  Some programs have a tool to point out its presence, like

gcc

  with option "-Wtrailing-whitespace"

git
  with option "apply --whitespace=..."

  and in ".git/config"

[core]
	whitespace=...

grep

  with option -e ' $'

less

  with command "/ $"

mandoc -T lint

  default action
]
