weird version_tuple when hardcoding version_scheme

[nschloe]

I would like to use setuptools_scm to append a git sha if applicable, and in any case use a hard-coded version number as base (instead of a Git tag). To this end, I use the "version_scheme":

      use_scm_version={
          "version_scheme": lambda _: "4.1.0",
          "write_to": "foobar/version.py"
      }

The command

python3 setup.py --version

correctly produces

4.1.0+g4ac9d2c

but the version_tuple in version.py is weird:

version = '4.1.0+g4ac9d2c'
version_tuple = (4, 1, '0+g4ac9d2c')

I would have expected

version_tuple = (4, 1, 0, 'g4ac9d2c')
# or perhaps
version_tuple = (4, 1, 0, '+g4ac9d2c')

What's going wrong here?

this should use packaging.version to pick things apart correctly
