:) It's very easy. You checkout the Emacs source tree with git, then make your change, commit it with a message in Changelog format), test it, and finally use `git-format-patch HEAD~1` to save it as a .patch file. Then you can post it as an attachment to a report-emacs-bug email summarizing the issue and the proposed fix.

As a small bonus, this process ensures that you're credited for finding and fixing the issue in the Emacs history, which is nice :); also, it makes it easy for people to test the proposed fix (although, arguably, it's already easy in this case).

In general, you need to sign a contributor agreement to send patches to Emacs; this particular fix however counts as a "trivial" fix, and thus is exempted from this. But if you haven't yet done so, signing the CLA is very easy, and will make it smoother to contribute more significant patches in the future :)

That's right; nice catch. I'd suggest sending the patch to bug-gnu-emacs, and seeing if people have other similar insight.

Cheers and thanks for catching this issue and proposing a fix!
Clément.
