Problems that shell-quote-argument doesn't solve?  If so, can you show
those problems?

Why do you need such a command?  Emacs can copy text between buffers,
so you don't need to cons a string to insert it into another buffer.

In general, one should avoid strings in Emacs Lisp, because buffer
memory is handled much more efficiently than string memory.

buffer-substring?
