* the text should be wrapped to ~76 characters (to appease git viewing tools, mainly), unless you really need longer lines (e.g. for ASCII art, tables, or long links).
* the Fixes line goes after the body with a blank newline separating the two. (It is acceptable but not required to use a trailing period, such as `Fixes #12345.`).
* there is **no** Markdown in the commit message.
-* we **do not** use `Signed-off-by` lines. Don't add them. Our Gerrit server & GitHub bots enforce CLA compliance instead.
* when referencing CLs, prefer saying "CL nnn" or using a go.dev/cl/nnn shortlink over a direct Gerrit URL or git hash, since that's more future-proof.
* when moving code between repos, include the CL, repository name, and git hash that it was moved from/to, so it is easier to trace history/blame.
