Ah. I think if you want to undo a `pip install --user -e .` you can
just do `pip uninstall numpy`? But in any case the equivalent of 'pip
install -e' is 'setup.py develop', and the proposal is only to disable
`setup.py install`. So if you prefer `setup.py develop` then you could
still use it.

(IIUC `pip install -e` is a *very* thin wrapper around `setup.py
develop` -- normally pip takes over the job of actually installing
files, so pip gets to interpret options like --user and figure out
what it means for where it puts the files, but in the case of `install
-e` it looks like it just calls `setup.py develop` directly, so if
--user doesn't work it's probably because setup.py develop doesn't
know about --user?)
