no repo dependency on pypi allowed

[larsbuntemeyer]

If i have

[options.extras_require]
preproc = 
    pyintorg @ git+https://gitlab.dkrz.de/remo/pyintorg.git@v0.2.0a1
prsint =
    pydruint @ git+https://gitlab.dkrz.de/remo/pydruint.git@v0.1.0

in setup.cfg i can not publish on pypi due to:

Invalid value for requires_dist. Error: Can't have direct dependency: "pyintorg @ git+https://gitlab.dkrz.de/remo/pyintorg.git@v0.2.0a1 ; extra == 'preproc'"
