Which is because pp-buffer doesn't indent this, which is because
indent-sexp doesn't indent it, which is because indent-sexp now relies
on forward-sexp to find the end, and forward-sexp only goes over the

Another example:

With point before the (foo), Emacs 25 indent-sexp turns this

(foo) (blah

into this

(foo) (blah

Emacs 26 indent-sexp doesn't do anything from that position.  It's less
clear which is correct in that case, but restoring to the Emacs 25
behaviour would fix the #s(...) case as well.  Alternatively, we could
fix elisp sexp movement to handle such expressions, which we should
probably do anyway (see also Bug#15998).
