This patch adds a very simple install replacement script to git.
This allows more easy installation on systems that don't have a
compatible install.

Do you have a particular case where you need it?

No such thing here:
zsh$ /bin/sh
$ which getopts
$
Yes, bash and zsh do have that, but my (and I suspect many git users')
/bin/sh is neither of those. Git scripts should use just POSIX shell
features for portability.
Which is particularly important when you are trying to replace a common
utility, because the systems that won't have it are likely to not have bash
either.
You may want to have a look at /usr/share/automake-1.9/install-sh (or
/usr/share/automake<something>/install-sh). It shows how to portably process
options in shell and since it's in fact covered by the MIT/X license (and FSF
changes are public domain), git could just use it if necessary.

Are you sure reall install would do this? The maual (install(1)) states
following usage variants:
install [OPTION]... [-T] SOURCE DEST
install [OPTION]... SOURCE... DIRECTORY
install [OPTION]... -t DIRECTORY SOURCE...
install [OPTION]... -d DIRECTORY...
Now however there is nothing saying that SOURCE... is at least two, so is
install git /usr/bin
a case of the first or second usage? I would say the second, but your code
would:
rm -rf /usr/bin
cp git /usr/bin

./gitinstall "b*c" "a b c" /tmp
... will copy a lot of files to /tmp (presuming we are in git source
directory, where tons of files are called builtin-<something>.c) and complain
that there is no 'a', no 'b' and no 'c'.

We have some machines here where no compatible install was installed. Sure I
could have built GNU coreutils on all of them but writing this script was just
more convenient for me.

I just used it because the shells on my machines had it. My idea was that if
someone has a shell with less features we could still replace parts with even
more basic ways of doing things.

Oh, forgot about that implementation. Since this version is definitely more
advanced I retract my patch and propose to use that one instead.

I did not intend to write a full replacement for install but cover only the
cases needed to install git.

No, in your example /usr/bin is a directory and thus this is:
rm -rf /usr/bin/git
cp git /usr/bin

There are no files with special characters in git to be installed. Again this
was meant a _simple_ replacement for install on systems without a compatible
install just to install _git_, not to reinvent the wheel.
