b055001b6a hush: fix handling of unmatched ${name (without closing '}') - 
was eating all remaining input, potentially megabytes.
nofork: save/restore die_jmp too
nofork: use -2222 instead of -111 as "special" return valur for zero
(-111 is used by some applets. -2222 won't fit in exitcode and thus safer)
