Ok; patch attached :) Here's a test case:

    ~this~~won't~~work~
    ~but~​~this~​~will~
    ~and~⁠~so~⁠~will~⁠~this~

    ⇒ <code>this~~won't~~work</code>
      <code>but</code>​<code>this</code>​<code>will</code>
      <code>and</code>⁠<code>so</code>⁠<code>will</code>⁠<code>this</code>

You can see the difference in behaviour by resizing the browser window: the 
second line will break at code boundaries (it uses zero-width spaces) while the 
second line will stay together (it uses word joiners, aka zero-width no-break 
spaces)

I detailed the change in the commit message.

I agree, though this seems non-trivial.  Here's another idea (I don't know how 
it compares to other options :): src_<lang>[]{} could be extended to allow 
different delimiters; this would make it more widely usable. For example, the 
following forms would all be equivalent:

    src_elisp[…options…]<…code…>
    src_elisp[…options…]“…code…”
    src_elisp[…options…]⟨…code…⟩
    src_elisp[…options…]«…code…»

This is inspired by LaTeX's \verb syntax, but using paired delimiters.  The 
nice part of this is that it would solve the current issue that makes 
src_<lang> not always usable, namely unmatched curly braces:

    #+PROPERTY: header-args :exports code
    src_elisp{(defun foo () ?})}
    ⇒ <code class="src src-lisp">(defun foo () ?</code>)}

    #+PROPERTY: header-args :exports code
    src_elisp{(defun foo () ?\})} is an ELisp function
    ⇒ <code class="src src-lisp">(defun foo () ?\})</code>
