[PATCH v4 0/2] Support marking .git/ (or all files) as hidden on Windows

Windows does not share Unix' convention that files and directories whose names start with a dot are hidden. Hence `.git/`, for example, is in plain view, and caused quite a bit of trouble: some users wanted to peek inside and did not understand what it contains, others modified files.

There was a stream of bug reports, until Git for Windows introduced the (opt-out) option to hide at least the .git/ directory by default. The option is configured via the config setting core.hideDotFiles, with the possible values false, true and dotGitOnly (the latter being the default).

This is a heavily version of patches we carried in Git for Windows for way too long without submitting them upstream.

This iteration addresses Junio's most recent round of concerns.

Johannes Schindelin (2):
  mingw: introduce the 'core.hideDotFiles' setting
  mingw: remove unnecessary definition
