Hi Robin,

sorry, I did not notice that my version of git-send-email does not seem to understand "--subject-prefix".
Should I re-send my two patches with a proper subject line?

Cheers
René

Hi René,

thanks for the patches!  You don’t have to resend them, I’ll have a look
at them later today or tomorrow.

Best,
Robin

Hi Robin,

I hope you had a happy Easter!
Could you have a look at my PRs if you find the time? :)

Cheers
René
