bug#66317: Project mode-line

[Juri Linkov]

> One interesting bug: project-switch-project causes the modeline project
> name to change for all buffers.

> then while I'm at the find-file prompt, all modelines for all buffers
> show emacs-29 as the current project, no matter what they showed before

I don't see this bug because I'm using other-project-prefix from bug#63648 ;-)
