use other language with opt_interactive()

[rwaaijman]

When using opt_interactive(), standard the english language is used (search, next, previous, etc). Would it be possible to change language? Or set yourself the terms?

[rich-iannone]

It is not yet possible but, as a next feature, the locale value should automatically set these labels to the locale's language. In addition to that, we will have a helper function to manually set the labels.
