Why does more(1) not leave an exit status?

[rouben at math9.math.umbc.edu]

On a couple of different systems I have tried, more(1) always exits
with status 0.  I would have expected more(1) to exit with a not-zero
status when invoked with a non-existent file as its standin.

Both cat(1) and tail(1) exit with status 1 when trying to open a 
non-existent file.  Why not more(1)?

Is this due to an oversight or due to a conscious decision?  Does 
anyone know?
