Fix issues reported by CSpell

I did not correct "sigup" because this string may be used by others to modify the form. This should be fixed in the next major release.

Well looking at all the typos I have is kind of embarrassing! Ha! Thanks for this. Marking as to be ported. It's merged into 4.x branch for release. Thank you for the help!

Started a 5.x branch and included this change.

Thanks. The default branch in GitLab could be updated. Also, there are some obsolete issue branches and tags in the repo that could be deleted.

Thanks - I had forgotten about your other comment. Updated default branch to 4.x (for now) and also removed old issue branches & some of the weird tags.

The latest commit on 4.x (475d692) introduces a spelling error. That commit should be merged into 5.x. Since this issue is now committed to 5.x, it can probably be closed.
