Originally peektoken in Busybox ash was the same as in dash.  It then
changed to effectively act as nexttoken_ends_lists but the name was
retained until Denys's patch.  Reverting that patch changes the name
but retains the old behaviour.  The following patch changes the behaviour
to match that of dash.

It works.  Busybox builds at each commit and the tests pass or fail
as appropriate.
