Title: more specialize search for ascii

@which search("howdy",'\n')
has been dispatching to search(s::String,c::Union(Set{Char},Char,AbstractArray{Char,1})) at string.jl:194
rather than the specialized ASCIIString version

Passes 'make clean testall'. Please note that is my first pull request to /base.
