Merge branch 'nd/gitignore-trailing-whitespace'

Trailing whitespaces in .gitignore files, unless they are quoted for
fnmatch(3), e.g. "path\ ", are warned and ignored.

Strictly speaking, this is a backward incompatible change, but very
unlikely to bite any sane user and adjusting should be obvious and
easy.

* nd/gitignore-trailing-whitespace:
  t0008: skip trailing space test on Windows
  dir: ignore trailing spaces in exclude patterns
  dir: warn about trailing spaces in exclude patterns
