[PATCH 0/2] Refuse to write to reserved filenames on Windows

["Johannes Schindelin via GitGitGadget" <gitgitgadget@gmail.com>]

On Windows, for historical reasons, file names such as aux.c, nul.txt are
not allowed. For aux.c, attempts to write such a file will result in an
obscure error, for nul.txt the call will succeed but no such file will
appear, ever, instead the effect will be equivalent to writing to /dev/null 
on Linux/Unix.

Let's help users by refusing to create such files altogether, with an
informative error message.

Johannes Schindelin (2):
  mingw: short-circuit the conversion of `/dev/null` to UTF-16
  mingw: refuse paths containing reserved names
