This prints a hint about using `jj new <first conflicted commit>` and `jj squash` to resolve conflicts. The hint is printed whenever there are new or resolved conflicts. I hope this hint will be useful especially for new users so they know which commit to resolve conflicts in first. It may not be obvious that they should start with the bottommost one. I hope the hint will also be useful for more more experienced user by letting them just copy the printed command without first running `jj log` to find the right commit..

New conflicts appeared in these commits:

|
kkmpptxz e301deb3 (conflict) (no description set)
|
|
To resolve the conflicts, start by updating to it:
|
|
jj new kkmpptxzrspx
|
|
Then use `jj resolve`, or edit the conflict markers in the file directly.
|
|
Once the conflicts are resolved, you may want inspect the result with `jj diff`.
|
|
Then run `jj squash` to move the resolution into the conflicted commit.
