Follow-up Comment #2, bug #50416 (project octave):
> Looking in dir.m I see a loop (bad) that uses fullfile.
> Since the directory portion 'fn' is always being pre-pended it would be
faster to use strcat here.
> [...]
> This was only a quick test, you might need to actually convert 'fn' to a
proper directory using fullfile just once, and then use strcat, but the result
is basically sound.
Actually, fullfile can take a cell array of filenames directly.
