Yes, but there are other options, that reset dependent options, just like
'rnu' resets 'nu' currently (well there is a patch pending that changes it)
Or the 'diff' option resetting a whole bunch of dependent options.

And this is what I have now changed in your patch. If setting 'vts'
or 'vsts' the dependent 'ts' and 'sts' options will be reset and when
clearing the 'vts'/'vsts' option the dependent 'ts' and 'sts' options
will be reset to their value before variable tabstops where active.
Also setting 'ts'/'sts' when 'vsts'/'vts' is active will disable
it. This seems to work so far.

I'll need to update the test for this change, and then I'll post an updated
patch soon.

regards,
Christian
