Future of removeTrailingWhitespace

[sjakobi]

With #139 merged, rTW is no longer necessary for the scenarios for which it was originally created. Should we deprecate and remove it now?

A few thoughts:

• rTW is still useful as a one-stop shop for addressing trailing whitespace
• We should at least document that rTW is less useful than it used to be

See also the regression discovered in #205 on why post-precessing trailing whitespace isn’t such a bad idea ;-)

I’ve seen the trailing whitespace cycle a couple of times now – it’s fixed, ah wait no, but now it’s fixed, ah wait no. It’s one of those problems that sound simple but totally aren’t :-(
