[0.4.2] run epf error return values buglet?

[glenn@mathcs.emory.edu (Glenn Barry)]

A unix cmd executed within the scsh run epf that returns a non-zero
value has that value multiplied by 256:

> (run (grep blah /etc/motd))
256

> (run (wc /blah))
wc: cannot open /blah
512

Same behavior for SunOS 5.5 and 4.1.1 and Irix 5.3.

Bit-shifting bug or feature?

thx,
glenn
