Yes, but it was not clear from the report that it is also the text of
the error message you see.  Thus my question.

But that's not what happened.  man.el actually tries to find the man
page by itself, and displays that message if it fails.

Patches to make the diagnostic smarter in this case, including
figuring out what to use instead of "..." above, are welcome.
