Has strikethrough been implemented?

[Charliedean]

There are few references to "strike" in the code but no public documentation on how to use it.
Is it currently implemented? If not is this currently being tracked for addition?

For anyone interested - I manually applied the strikethrough like the following:
t.font._element.attrib['strike'] = 'sngStrike'

Just used the workaround above... Any chance that strikethrough will be added for real?

... or asked differently: what is still missing in #606 ?
