Git trailing blank lines feature configuration

[Thomas Nemeth <tnemeth@free.fr>]

    Hi !

    I have the habit to keep 1 blank line at the end of my files. To me,
    it eases the EOF modifications (selecting code blocks, pasting them)
    in vim.

    Note that I still want to remove blanks at EOL. But I'd like to keep
    1 blank trailing line. I still can, of course, but the diff still
    shows me a red "+"...

    Would it be possible to have a configuration option to avoid warnings
    (because I see that as a warning) about trailing blank lines ?

    Thanks

Thomas.
