User visible:
* Also accept the git install path (and not the mingw64 subdir) as a user
supplied install location. Make it the new default and warn the user if
a mingw64 dir is supplied (=this dir is not checked, so it might be
anywhere...)
* Find git.exe in path and use that as an install location
* Add error|status messages and output less noise (robocopy)
* do some check if column.exe is not found...
* adjust the installation text for windows...
not user visible:
* more.exe does not work when used in a cmd which has a unicode codepage
-> save the current codepage and set a sane default during the install
* do some "magic" with quotes around path variables -> makes it work with
pathes with spaces in it (both final git dir and the git-extra checkout)
* Do not leak variables to the sourounding interpreter
The script install.cmd has two environment variables PREFIX and HTMLDIR.
PREFIX is where your git is installed and HTMLDIR is the location of html files under PREFIX.
This script is written for msysgit installed from https://github.com/git-for-windows/git.
