This option stops git mergetool from aborting at the first failed merge.
This allows some additional use patterns. Merge conflicts can now be
previewed one at time and merges can also be skipped so that they can be
performed in a later pass.
There is also a mergetool.keepGoing configuration variable covering the
same behaviour.
