[PATCH v2 0/5] Fix make check-docs on Windows

I stumbled across this when investigating one of Duy's bugs in the CI builds.

Changes since v1:

 * We no longer add an extra space in front of the $(patsubst ...) in the
   second loop, but fix the underlying bug that prevented check-docs' part
   from working where it discovered documented commands that are actually
   not installed.
 * As a fall-out, the gitremote-helpers page, which does not refer to a
   command, but to a concept, was moved from section 1 to section 7.
 * As a second fall-out, the documentation for git remote-testgit, which is 
   a command, but not installed, was removed.
 * As a "while at it" patch, the part of the check-docs target that tried to
   identify commands that are listed in the help, but not implemented, was
   fixed to no longer mistake guides like gitattributes and gitcli for
   commands.

Johannes Schindelin (5):
  docs: move gitremote-helpers into section 7
  docs: do not document the `git remote-testgit` command
  check-docs: really look at the documented commands again
  check-docs: do not expect guide pages to correspond to commands
  check-docs: fix for setups where executables have an extension
