Fix remaining existing tests.

XTRACE output for builtins with assignment arguments added.
Note difference as the output is assignment-like too:
  'foo=<squggle><squiggle>bar'
now appears as
  foo='<squiggle><squiggle>bar'

Remove stupid "int htok" that stopped name part of scalar being expanded.

Rewrite KSH_TYPESET test to use old builtin interface where this applies.
