[PATCH v3 0/3] bin-wrappers: test without dashed commands in PATH

This patch series allows running the test suite and/or running an uninstalled build without dashed commands in the PATH.

Changes since version 2:

   merged - The first 3 old patches (fixes to tests to avoid dashed
         commands, and added GIT_TEST_INSTALLED documentation) are
         now in master, so I am not duplicating them here.

   1/3 - Changed to use "@@BUILD_DIR@@" instead of "__GIT_EXEC_DIR__"
         for sed substitution, and to use single quotes around it
         when setting environment variables in wrap-for-bin.sh.
         But this patch still does not really try to handle
         strange characters in $(shell pwd); see earlier email
         thread about this.  (This is newer than pu.)

   2/3 - Fixed a couple of spelling errors in the --with-dashes
         documentation, and avoid "TOP".  (This is newer than pu.)

   3/3 - Replaced wording for running an uninstalled git.
         It now uses Junio's text: no change compared to his
         version of this patch that is currently in pu.

Matthew Ogilvie (3):
  build dashless "bin-wrappers" directory similar to installed bindir
  run test suite without dashed git-commands in PATH
  INSTALL: document a simpler way to run uninstalled builds
