Whitespace options

Hi all,

I think there should be a whitespace option that ignores lines that consists completely of whitespace vs lines with actual trailing whitespace preceded by non-whitespace.

The reason is that many editors (especially those supporting indent- based code folding) keep 'empty' lines at the current indentation level. git (with default settings) flags all those lines.

I know I could just remove 'trailing-space' from 'core.whitespace', but I would actually still like be notified about the case where a line that is not whitespace only ends with trailing whitespace.

Thanks

Gerd
