commit 9545519572d47b4712f27e53e7b64bf88d473877

Commit: Jackson Ray Hamilton <address@hidden>

    Add open/close parenthesis syntax to “<” and “>” in JSX
    
    * lisp/progmodes/js.el (js-jsx--syntax-propertize-tag): Like in
    sgml-mode, treat “<” and “>” like open/close parenthesis, making the
    text more navigable via forward-sexp, etc.
