Manual revert of elpendor#9

elpendor#9 was a buggy PR and it seems to have introduced a bug (elpendor#10, elpendor#12). The PR claimed to fix a major issue where all attempts without `-p` would fail, but I can't replicate it.

Since I had already created a PR with elpendor#11 it doesn't seem to be possible to simply revert elpendor#9 with the Github button. So I'm doing it like this.
