[PATCH v2 0/2] Fix use of strategy options with interactive rebases

The interactive machinery for git rebase can accept special merge strategies or strategy options, but has a bug in its handling of strategy options. This short series patches that.

Changes since v1:
  - Small change to the second commit message
  - Addition of a cover letter.  :-)
