Subject: 29.4; Symbols joined during parsing with .erts files
Date: Mon, 01 Jul 2024 16:50:00 -0700

To reproduce, run `emacs -Q`, paste the following into test.erts and run
the test using C-c C-c.

Name: Simple
Code: (lambda ()
        (let ((l '(x
                   x)))
             (insert (prin1-to-string l))))
No-After-Newline:
=-=
=-=
(x x)
=-=-=

The buffer contents should be "(x x)" after the transform runs but the
actual contents are "(xx)" as the two x's seem to be getting joined
during the parsing process. It only seems to happen when two symbols are
separated by a newline plus some whitespace as above. When the newline
between the x's is removed, the test passes as one would expect.
