I took a look in the doc/ directory of the upstream tarball and found
something strange: fulla.pod still mentions a -s switch but fulla.html
does not. There are more differences:

fulla.pod:     -b -c -d -e -f -g -h -i -l -m -n -o -p -r -s -t -v
fulla.html: -a -b -c       -f -g       -l -m -n -o -p -r    -t -v

(all taken from the tarball from
http://sourceforge.net/projects/hugin/files/latest)

As i experienced the behaviour with any image i tried i omit an image to
keep this reply less bulky. A command line that reproduces the issue would
be as this:

fulla -s -g -0.004318:0.039896:-0.096925:1 -o a.jpeg image.jpeg
fulla    -g -0.004318:0.039896:-0.096925:1 -o b.jpeg image.jpeg
md5sum a.jpeg b.jpeg

With any random image i tried this gives identical a and b files even though
the -s switch is supposed to cause fulla not to rescale the image. These
parameters are for correction a 24mm Lens so they are stretching the image
in the corners (which should result in a lager image than the original if
not trimmed).
    Maybe fulla behaves different if the parameters are not for correcting
barrel but for pincushion distortion (which i didn't need to yet). If this
is of any help i can hand in according further files/parameters.
