A way to distinguish between pip installed packages and those from teh system package manager in pip list when not in a virtualenv

@dstufft suggested I file this.

In theory, the PEP 376 INSTALLER file should allow pip to determine this. Even if other tools set it incorrectly (or don't set it at all), pip should be able to distinguish between "installed by pip" and "installed by something else".

Interesting - should make it visible in pip show also

This is now the case with pip show --verbose your_pkg.

@alex Is pip show --verbose pkg sufficient for you? It's also possible to get this information with a short script using pkg_resources:

from pkg_resources import working_set
for dist in working_set:
    print(f"{dist.project_name} {dist.version} {dist.location} {dist.get_metadata('installer').strip()}")

Is that sufficient, or do you need more?

Closed by #4414.
pip list -v will now print the installer.
