pre_prompt bug when generating from current folder #1972
Description
- Cookiecutter version: 2.4.0
- Template project url: N/A
- Python version: 3.10
- Operating System: Linux
Description:
I just learned about the new pre_prompt in 2.4.0. It's exactly what I wanted. Thanks for the new feature. When I develop the templates sometimes I will just run the cookiecutter in the same directory: cookiecutter .. With pre_prompt defined it will crash with an error saying the temporary directory already exists:

It seems the temporary sub-directory name depends on the directory name of the repository, "." probably resolves to nothing and it will try to create the parent directory instead, so if I use the absolute path of the current directory it works: cookiecutter $(pwd). It feels like a possible fix is just to compute the absolute path of the input path first. Thanks.
