"Preview a previous version" anti-feature?

[j-ulrich]

I think this "preview a previous version" (#187) is an anti-feature because:

• The [//]: # s-${version} and [//]: # e-${version} metadata clutters the resulting output.
• It limits the plugin to markdown. Before, I think it was possible to generate other formats simply by using a different template.
• This functionality seems to be misplaced in the plugin because the plugin is about generating a change log and not about parsing resp. extracting something from it. This sounds like a responsibility for a change log parser.

I guess the first two points could be fixed by making the metadata configurable.

What do you think about these points?
