Some editors (like the vim variants), when seeing "trim_whitespace"
decide to do just that for all of the whitespace in the file you are
saving, even if it is not on a line that you have modified.  This plays
havoc with diffs and is NOT something that should be intended.

As the "only trim whitespace on modified files" is not part of the
editorconfig standard, just move the whole thing off to the
Documentation/ directory so that those that wish to use such a thing can
pick it up from there.

If trim_trailing_whitespace is the only rule that has actually been a problem,
how about removing it and leaving the rest of .editorconfig intact?
The other rules are still useful to have as defaults.

+1

The trim_trailling_whitespace can be removed. IMHO the main point of
the .editorconfig is to set up the correct indentation, that is to say
the indent_style and indent_size parameters, and I don't think that
anyone is having issues with these so far.

This would not solve the issue, because it would still apply for
anything under Documentation/*

Good idea, let me do v2 with that...
