-> This is not new behavior in 2.2 as far as I know. Ikiwiki was always
-> interpreted "[ [foo bar] ]" as a preprocessor directive, with the
-> whitespace after the first word being the significant bit that
-> distinguishes it from a wikilink. If you want whitespace in a wikilink,
-> you use underscores; there's been a note at the end of [[WikiLink]] about
-> that for some time. --[[Joey]]
