Please read https://github.com/cplusplus/draft/wiki/Commit-message-format in its entirety, adjust the commit message, and force-push.

The commit message is still missing "Fixes US 113-173 (C++26 CD)."

Having this in the pull request is good, but not enough. And we don't want "also fixes", because this is a genuine editorial issue, not an application of a paper or LWG/CWG issue resolution (as approved by plenary).

And while we're at it, "rm" is not an English word.

[JeffGarland]

sorry @jensmaurer, still learning the rules. Hopefully it's right now.

@JeffGarland it's easiest if you look at the other PRs labeled ballot-comment for guidance. There should be a single commit with title/first line:

[meta.reflection.extract] Remove second "constexpr" in if statement

The second line of the commit message should be:

Fixes NB US 113-173 (C++26 CD).

[JeffGarland]

Thx @eisenwave - done.

@JeffGarland , thanks for the updates.

Could you now please squash the two commits and force-push, making sure the merged commit message is correct? "git log" helps to find existing, similar commit messages. As a bonus, please also adjust the title of this pull request to match the first line of the commit message.

Thank you.
