Re: 31.0.50; tab-bar-formal-global erased global-modeline-string's mouse hover/click action menu

Thank you, I’ve forwarded the email to bug-gnu-emacs@gnu.org.

Another question: how do you add rich text to emails? 

I'm reading the Emacs-devel email archives, and the code in the email body is 
plain text with a white background and black foreground. If we could display 
code with syntax highlighting in emails, that would be great.
