templatekw: add default implementation of _hybrid.gen

This is convenient for new template keyword, which doesn't need to support
the legacy list hack (provided by _showlist()), but still wants to have
a string representation.

Test UI worker interaction

  >     for arg in args:
  >         ui.status('run\n')
  >         yield 1, arg
  > cmdtable = {}
  > command = cmdutil.command(cmdtable)
  > @command('test', [], 'hg test [COST]')
  > def t(ui, repo, cost=1.0):
  >     cost = float(cost)
  >     ui.status('start\n')
  >     runs = worker.worker(ui, cost, runme, (ui,), range(8))
  >     for n, i in runs:
  >         pass
