The change f2a037fb7b had unfavorable
effect of making hexdump to return non-zero exit value always.
This happen because oversight when 'exitval' gets to be set. By clance,
one might expect main() to call next() which will return value for
'exitval'. That assessment misses later call chain main() -> display()
-> get() -> next(), which in reverse should return correct value for
'exitval'.
It was mentioned in util-linux maillist that Ondrej Oprala is working on
major renewal of the hexdump . That in mind it seems best to simply to
revert the global 'exitval' and avoid conflict with Ondrej's work.
