Subject: 30.0.50; 13-years old commented code in src/data.c:1608 (set_internal)

Hello,

While reading the sources, I found the following commented piece of
code in set_internal:

  /* If restoring in a dead buffer, do nothing.  */
  /* if (BUFFERP (where) && NILP (XBUFFER (where)->name))
      return; */

This code has been changed 13 years ago and also commented immediately
(in the same commit):

Try and fix unbind_to when localness of binding has changed
* eval.c (unbind_to): Don't unbind a local binding into the global
binding when the local binding disappeared.  Inversely, don't unbind
a global binding into a newly created local binding.
* data.c (set_internal): Make its `buf' arg into a `where' arg so we
can specify the frame to use, when applicable.  Adjust callers.

-  if (buf == 0)
-    buf = current_buffer;
-
   /* If restoring in a dead buffer, do nothing.  */
-  if (NILP (buf->name))
-    return;
+  /* if (BUFFERP (where) && NILP (XBUFFER (where)->name))
+      return; */

I assume that after 13 years, it is safe to remove it.
