If you are commiting to a tree-wide fixup, I think its best to get the
just Error ** version in use tree wide and just drop may_fail and
no_fail variants.
The only reason to add a second fn would be to avoid having to touch
all the call sites which you have now done.
Ultimately there should be one API used by all no_fail and may_fail
call sites that accepts an Error **. "no fail" callsites pass in
&error_abort. I think this is what you were suggesting in P1?
I don't see this change as being much more minimal and it's at the
expense of correctness.
Regards,
Peter
