You are right about this. Here the why. I have been the one introducing sbug in
pw(8) when I rewrote it, but since the beginning while I found this was better
than the solution in place I didn't like adding another external lib just for
that.
Fair enough.
Short after I discovered about open_memstream(3) and figured it could fill the
same spot here but keeping the dep only on libc.
I keep forgetting that open_memstream(3) is even a thing. `grep'ing the src tree, it looks like it's very rarely used.
I was puzzled about pushing
this change, and the switch to git reminded me about some uncommit patches
sitting on my tree and I ended up pushing it.
If people have strong opinion I can revert it back.
I can't imagine anyone having a problem with this. :-)
Thanks for explaining.

Things that have not been taken in account in the change, but to answer
questions asked privately:
- I have performed absolutely no performance benchmark, it does not matter here.
- The size of the final binary is smaller:
- 76k on amd64 for the new version
- 77k for the old version
Best regards,
