[PATCH v2 0/3] Make the tests that test core.hideDotFiles more robust

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

We have this feature on Windows where the files starting with a dot can be
marked hidden (whether a file is hidden by default or not is a matter of
naming convention on Unix, but it is an explicit flag on Windows). This
patch improves the regression tests of this feature, and it has been carried
in Git for Windows for over three years.

Junio, I'm sorry that I did not get to send v2 yesterday, and that you spent
time on the two add-on patches even after I finalized this second iteration
(but I was first waiting for the PR build to pass and while that happened, I
got stuck in meeting after meeting).

Changes since v1:

 * A preparatory patch now moves and renames is_hidden to 
   test-lib-functions.sh
 * A typo in the function's comment is fixed, while at it.

Johannes Schindelin (3):
  t: consolidate the `is_hidden` functions
  mingw: make test_path_is_hidden tests in t0001/t5611 more robust
  t: fix casing of the operating system `Windows`

     -    mingw: make is_hidden tests in t0001/t5611 more robust
     +    mingw: make test_path_is_hidden tests in t0001/t5611 more robust
     +
     +    This function uses Windows' system tool `attrib` to determine the state
     +    of the hidden flag of a file or directory.
      
          We should not actually expect the first `attrib.exe` in the PATH to
          be the one we are looking for. Or that it is in the PATH, for that
          matter.
      
     +    Let's use the full path to the tool instead.
