Cannot create requirement from this particular pip freeze output

[skrawcz]

If you install a package in a subdirectory from git, e.g.

git+ssh://git@github.com/my/repo.git@project25#egg=PACKAGE_NAME&subdirectory=SUB_DIR/

and then do a pip freeze you'll instead get:

PACKAGE_NAME @ git+ssh://git@github.com/my/repo.git@3684f02bf928cae39d10d1d9b478d95d2267b2af#subdirectory=SUB_DIR/

In which case this cannot be parsed (redacted with parts I can't share):
