Here's AIX 3.2.5.  If it doesn't answer your question, let me know.

    $ cat j
    \n(.c '\n(.F'
    .lf 42 mol
    \n(.c '\n(.F'
    .lf 314
    \n(.c '\n(.F'
    .lf \n(.c \n(.F
    \n(.c '\n(.F'
    \n(.c '\n(.F'
    $ nroff <j | sed -n /./p
    1 '<standard input>'
    41 'mol'
    312 'mol'
    312 'mol'
    313 'mol'
