hi @xi,
thanks for the fix and the link to the docs! We are currently still in the process of clarifying some issues around accepting PRs from external contributors and I would therefore refrain from merging your PR until we resolved them :/ We discussed the change and generally agree that we would like to fix the non-standard signature dashes. If you don't mind I would open a new PR and close this one so it is included in the upcoming release

It feels a bit strange to be an "external contributor" when most of the commits in this repo were created by me 😄. But true, it's been a few years. For a small change like this I see no harm in creating a new PR if that makes things easier for you.

fair point ;-) It's sadly about legal things though, not experience :) Will make a new PR tomorrow
