-    Fix buffer overflow in Markdown parser
-    
-    This fixes a buffer overflow that happened when parsing a bad Markdown
-    file with an unclosed emphasis nested in other elements, such as
-    
-    ```markdown
-    > __af_err af_flip(af_array *out, const af_array in, const unsigned dim)__
-    ```
-    
-    This snippet comes from the ArrayFire repository [1]. The problem was
-    found after the refactoring [2] that introduced std::string_view in the
-    code. The `std::string_view::operator[]` has bounds checking enabled
-    when the macro `_GLIBCXX_ASSERTIONS` is defined, which is the case of
-    Arch Linux build system.
