In addition, one can now specify an explicit version of the page, using the `@<version>` notation, similar to what is used for `source:` links (as discussed in #2635).
The CamelCase wiki links ''don't'' support arguments, but they do support a version specification (and still support a fragment identifier).
Some examples:
- see WikiStart@...
- see WikiStart@...#svntrac
- wiki:WikiStart?format=txt
- wiki:WikiStart@...?format=txt
