This has been solved/implemented in two git commits:

commit ef2eb3589883dc6ced661e424f0e11bee05cc83b

    * info/man.c (check_manpage_node):
    Call get_manpage_node if exit status from man -w PAGE was 2.


commit 8520d2b4d80eebe49ed44f11c47901f87d35c29f

    Check for man page with 'man -w'

    * info/man.c (check_manpage_node): New function, to check if
    man page exists with 'man -w'.  This is much faster for large
    man pages.
    (find_man_formatter): Cache return value.
    * info/info.c (get_initial_file): Use check_manpage_node instead
    of get_manpage_node.

    'info -w ffmpeg-all' was reported to be slow by Hilmar Preusse.
    'ffmpeg-all' is an especially long man page, so takes a longer time
    for nroff to format.
