Thanks for reassuring. As you can see in the log I once did care but
this time thought it is no longer worth the hassle.

Which raises the question what the API of `rst.el` is. So far I was
convinced that nobody will use any function from `rst.el` - so I'd
think that nobody is impacted by refactoring even if I change
signatures of functions. Of course I may be wrong.

Apart from that I'd think the interactive functions are the *real*
interface of `rst.el` which is interesting. Refactoring, however, by
definition does not impact this behavior. Debugging and those minor
changes in behavior which I did during refactoring I did document,
however. Where key bindings are impacted I defined aliases for renamed
functions so older key bindings should continue to work.

In other languages you have this public / private concept. I remember
that in Emacs you started using a double dash in identifiers to mark
them private. For example


would be part of the public interface, while


would be an internal function not meant for public use.

Is that correct? Are the examples valid?

If so, I'd probably like to mark internal functions this way. That
would be a good idea IMHO.
