Right.  You'll get warnings about the blank lines if the CHECKSTYLE
register is set to 3 or more.

Once again the non-printing input break comes to the rescue.  Here's how
I'd do it.

[[
.TH foo 1 2022-05-09 "groff test suite"
.P
Here is an example.
.RS
.P
.EX
$ \c
.B printf \[dq]\[rs]n\[rs]nfoo\[rs]n\[rs]n\[rs]n\[rs]n\[rs]nbar\[rs]n\[dq]
\&
\&
foo
\&
\&
\&
bar
.EE
.RE
.P
That was an example.
]]

There are of course many other ways to achieve the same goal, if one
strays beyond the portability advice offered in groff_man(7) (to be
found in groff_man_style(7) in groff 1.23).

In a *roff document that was not a manual page, I'd use the 'sp' request
or a macro package's wrapper for it, if one were present.
