`git commit -v` by default

Question

How can I configure git commit to act as git commit -v (showing the full diff being committed) by default?

Using an alias is not quite satisfactory, as it does not affect commit message editing during operations which may indirectly commit, such as git rebase.

If you are using git 2.9, this can be done with a config.

git config --global commit.verbose true

Git 2.9.0 Release Notes: https://github.com/git/git/blob/v2.9.0/Documentation/RelNotes/2.9.0.txt

"git commit" learned to pay attention to the "commit.verbose" configuration variable and act as if the "--verbose" option was given from the command line.
