hmm I don't like that. I want section ids as simple as possible to make
linking to them simple. And I want to keep section links as steady as
possible even when restructuring a document. I know this isn't
completely possible...
I though about it some time ago. I think it should work like this. When
the same headline is used multiple times then I'd like the following
ids:
headline
headline1
headline2
This makes sure headlines and ids still match in most cases and existing
links do not break. As long as the headlines are not duplicated in one
document you can move them around and change their level without
breaking any links.

Hmm yes this could make sense. Using no prefix for the usual pages and
adding one for sidebars...
I had a look at how to implement all this but something was more
complicated than I first thought so I didn't do it right away.
Unfortunately I can't remember the problem :-(
Well for the problem of headings starting with digits... Hmm which chars
are allowed at start of an id?
Maybe we could add an underscore:
_3_ways_to_do_it
And then compensate for it when building the link:
[[foo#3 ways to do it]] would link to foo#_3_ways_to_do_it
as well as
[[foo#_3 ways to do it]] would.
