Is there a way to reuse the previous comment on a git commit?

Question

Occasionally I will drop into troubleshooting mode and commit/push a number of small but separate commits with a comment like, \"Troubleshooting the during

Answer 1

At first, I answered:

I guess git commit --reuse-message=HEAD does it

Then I thought that's not what you wanted and deleted it. Then life caught up and got AFK for a couple of hours. Anyways, despite an answer having already been accepted, I would have suggested:

$ git config alias.troubleshoot '!troubleshoot() { git add -u && git commit -m "Troubleshooting the $1 during deployment to Heroku."; }; troubleshoot'

And you use it the following way:

1. modify existing files
2. (eventually add untracked files)
3. git troubleshoot foo

Would commit changes (and eventually new files) with "Troubleshooting the foo during deployment to Heroku." as commit message.
