My patch already inserts a line "Invoking manual-program man-args
in the background" in the displayed buffer until formatting is complete.

I think you are right.  Exactly like e.g. `grep' displays the output
*grep* buffer with the text "Grep finished with no matches found",
so when `man' can't find a manpage, it should display a similar
error message in the man output buffer.
