Easily recover comment created within editor

[jesse-mm]

I was using git commit and my editor vim to add next to the subject line a body. After saving the commit message commit-lint rules declined the message.

Is there a way to retrieve the previous message easily and amend changes to make it pass the commit lint rules ?

We could set the git template in the git configuration but that's not what that property is meant for. git commit clears the COMMIT_EDITMSG file, the prepare-commit-msg hook could read out the message from a file (that is otherwise lose because of a precommit error) from a file and insert it in the COMMIT_EDITMSG file
