This just happens because the docs are pulled straight out of the manual <http://docs.julialang.org/en/latest/stdlib/base/#Base.ifft>, which is written in restructured text. The repl help mode doesn't do any processing on the source so you get that.
We're in the process of moving to a markdown-based system which will give much nicer output when possible.
