[PATCH v2 0/8] Assorted Documentation-related fixes

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

While working on better support for make check-docs on Windows, I noticed a
couple more things, e.g. some "commands" were reported as being listed but
not built, e.g. gitcli (i.e. the parts of command-list.txt that are marked
as "guide").

This patch series cleans up those loose ends: after this, make check-docs 
reports no issues on Windows.

Changes since v1:

 * There is now an extra patch that gets rid of the NO_INSTALL variable in
   the Makefile altogether.
 * The generate-cmdlist.sh patch now results in more robust code (thanks,
   Junio!).
 * Patch 2/7 has a much better commit message now, and instead of filtering
   out excluded commands from the command-list.txt, it expects excluded
   commands by looking not only at $(ALL_COMMANDS) but also at 
   $(EXCLUDED_PROGRAMS).
 * Instead of the fragile logic to generate 
   Documentation/GIT-EXCLUDED-PROGRAMS that I hoped would let me get away
   with less work, I now imitate the logic of GIT-CFLAGS (and the resulting
   patch is actually a lot easier to read).

Johannes Schindelin (8):
  remote-testgit: move it into the support directory for t5801
  Makefile: drop the NO_INSTALL variable
  help -a: do not list commands that are excluded from the build
  check-docs: allow command-list.txt to contain excluded commands
  docs: exclude documentation for commands that have been excluded
  check-docs: do not bother checking for legacy scripts' documentation
  test-tool: handle the `-C <directory>` option just like `git`
  Turn `git serve` into a test helper
