[BUG] git init doesn't respect `--template` like configuration variable init.templateDir and $GIT_TEMPLATE_DIR

The title says it all.

If I run `git init --template=~/path/to/my/template` I get the following message:

	warning: templates not found ~/path/to/my/template

But, if I run:

	$ env GIT_TEMPLATE_DIR=~/path/to/my/template git init

I don't get a warning and the template is used just fine.

If I configure the configuration variable `init.templateDir` to `~/path/to/my/template` and run `git init` I don't get a warning and the template is used just fine.
