@baskargopinath If the second commit is simply fixing an error introduced by the first commit, the proper fix is to revise the first commit to not introduce the error at all. That way, we avoid polluting the history with unnecessary commits.

@baskargopinath two other comments:

1. It's good enough for the commit message subject to state the WHAT part (no need for the HOW) e.g., Fix misalignment of person names. The HOW part can be in the body.
2. The max commit message body width is 72 chars. Looks like yours is unnecessarily narrower than that.
