Option to keep original commit message in goal=rebase-with-history

[ravirajkarasulli]

When I run imerge --goal-rebase-with-history, I see commit messages like below

imerge 'rebase_8.1': automatic merge 9-1

Could you please provide an option to retain the commit message of the commit being merged?
