Details:

See attached reproducer script.

N.B., 'end-of-file' is not the same thing as 'end-of-input'.  The end macro
set with .em in mdoc works fine.  It's "interstital" pages that are the
problem.

Output of reproducer script follows.

mdoc-test(7)

NAME
     mdoc-test -- a correctness test for groff's mdoc implementation

Description
     When rendering multiple man page documents, a partially-collected line
at
     the end of an mdoc(7) page would not be flushed before rendering the
next
     page, omitting that line and the page footer from the output.  The next
     man page would emit the partially-collected line from the previous page
     between its header and summary.
