There appears to be a simple typo in the documetation:

https://www.gnu.org/software/emacs/manual/html_node/eintr/message.html#message

"The whole string between double quotation marks is a single argument
and is printed in toto"

....in toto ????

I'm a noob to emacs!!
Many thanx for all the work that the emacs team (past, present,
future) does to keep this software moving forward.
