Bug in json-patch-ot transforming multiple equal str_ins #941
Description
When transforming changes in markdown a typical scenario is completing task lists.
- task
to
- task
When transforming multiple edits to this we typically end up with
- [xx]
since equal str_ins operation are not merged into one.
It also seems more correct to merge equal inserts at the same position.
I prepared a PR fixing this: #955
NB: all tests pass, the formatting errors stems from lots of places not changed in the PR.
