Well, if there were install-sh script in git sources, we could uncomment

  #AC_PROG_INSTALL          # needs install-sh or install.sh in sources

line in configure.ac, then ./configure would automatically detect and
select 'install' program or script to use.  The autoconf documentation
(autoconf.info) says:

  This macro screens out various instances of `install' known not to
  work.  It prefers to find a C program rather than a shell script,
  for speed. [...]

  Autoconf comes with a copy of `install-sh' that you can use.  If
  you use `AC_PROG_INSTALL', you must include either `install-sh' or
  `install.sh' in your distribution, or `configure' will produce an
  error message saying it can't find them--even if the system you're
  on has a good `install' program.  This check is a safety measure
  to prevent you from accidentally leaving that file out, which
  would prevent your package from installing on systems that don't
  have a BSD-compatible `install' program.

So I guess we should also prefer install program for speed, even if we
do not use ./configure script.
