With no file argument, fortune looks for a database named fortunes
in FORTDIR. The base system has not shipped that file since
0538d7bbe620 (FreeBSD 12), only freebsd-tips, so the default
invocation failed even though a valid database remained. Callers
such as xlockmore's marquee and nose modes (fortune -s) then
displayed the error as the epigram.
If the named fortunes file is absent, scan every database in the
existing search path. /usr/local/share/games/fortune stays on that
path so fortune-mod-* packages keep working; when
fortune-mod-freebsd-classic restores the fortunes file, it is still
preferred. fortune -f with no arguments lists the same files that
would be searched.
