Is there an extension with a revset for 'all ancestors along the p1 line'?

[Sietse Brouwer]

I'm sorry, Gmail apparently breaks the In-reply-to header when you
change a message's subject. I provided a self-answer in the thread
"_firstancestors() is a built-in revset of all ancestors down the p1
line", or you can view it here:

Hopefully this message will have appear as in reply to my original question.

Apologies for the noise,

Sietse
