> Before you commit anything, check what you are about to commit.

Better still, check it as you commit, by enabling the config option commit.verbose (e.g. `git config --global commit.verbose 1`), so that the full patch that is to be committed is shown in COMMIT_EDITMSG, not just the file names that you touched. This removes the race condition between review and commit.

(While on this topic, I also recommend commit.cleanup = scissors, and reading through `git config --help`, or at least skimming it for basic familiarity with what options are available to you. A few more that I like: merge.conflictStyle = diff3, diff.algorithm = histogram, mergetool.keepBackup = false.)
