Hi,

attached is a patch that adds the option
delete-trailing-whitespace-if-on-empty for use in
delete-trailing-whitespace. Quoting from the documentation:

    Delete trailing whitespace before point on an empty line.
    If this is customized to nil, trailing whitespace will not be
    deleted if it occurs right before the point on an empty line.  For
    example,
    
        int main() {
            |
        }
    
    where `|' indicates the point, calling `delete-trailing-whitespace'
    with this variable set to t (the default) results in
    
        int main() {
        |
        }
    
    whereas if this variable is set to nil `delete-trailing-whitespace'
    will not change the buffer.

I'm not entirely sure if this should be an option, an additional
argument optional to delete-trailing-whitespace, or something else
entirely (or if this is not something other people find useful at all).
Opinions welcome!

  Tony
