close code block for PartialQuickSort

[udohjeremiah]

Closes the code block for PartialQuickSort which is currently:

"""
    PartialQuickSort{T <: Union{Integer,OrdinalRange}}

Indicate that a sorting function should use the partial quick sort
algorithm. Partial quick sort returns the smallest `k` elements sorted from smallest
to largest, finding them and sorting them using [`QuickSort`](@ref).

Characteristics:
  * *not stable*: does not preserve the ordering of elements which
    compare equal (e.g. "a" and "A" in a sort of letters which
    ignores case).
  * *in-place* in memory.
  * *divide-and-conquer*: sort strategy similar to [`MergeSort`](@ref).

  Note that `PartialQuickSort(k)` does not necessarily sort the whole array. For example,

```jldoctest
julia> x = rand(100);

julia> k = 50:100;

julia> s1 = sort(x; alg=QuickSort);

julia> s2 = sort(x; alg=PartialQuickSort(k));

julia> map(issorted, (s1, s2))
(true, false)

julia> map(x->issorted(x[k]), (s1, s2))
(true, true)

julia> s1[k] == s2[k]
true
"""

There seem to be many mistakes similar to the one pointed out above in many places in the Julia docstrings. I don't know much on Documenter.jl, but isn't this supposed to be an "error", hence not allowing such a docstring to compile?
