,----[ C-h f delete-trailing-whitespace RET ]
| delete-trailing-whitespace is an interactive compiled Lisp function in 
`simple'.
| (delete-trailing-whitespace)
| 
| Delete all the trailing whitespace across the current buffer.
| All whitespace after the last non-whitespace character in a line is deleted.
| This respects narrowing, created by C-x n n and friends.
| A formfeed is not considered whitespace by this function.
