> In practice, this probably won't have any effect on pybind11 except to make an exact copy of the pkg-config file. I wonder if there are other concerns about `--folow-symlinks`. I'll open a new PR for comment from others.

True in this case since the `sed` line doesn't do anything; the "danger" would be in case a replacement is really necessary, that it changes only one version of the file.

In any case doesn't seem very important so I dropped it here.
