The code doesn't like to see square brackets (actually, any ']') before
the ->, because then it cannot easily parse:
[[Some link]] with text intervening and [[another link -> another page]]
PmWiki interprets all of the above as being a single link to
Another Page with a link text of "Some link]] with text intervening
and [[another link". Although it's very easy to exclude a single
character such as ']' in a regular expression, it's a bit more difficult
to write a regular expression that excludes a sequence of two or more
characters such as ']]'.
One workaround is to use a character entity for the ']', as in:
[[Some Link [2005] -> Some Link]]
I admit this is ugly. Another way is to use the '|' form of link,
as in
[[Some Link | Some Link [2005] ]]
This works fine.
If you still need ']' to work in -> links, I'll work on it.
