Subject: Ensure button-get works in any buffer
X-Git-Tag: emacs-26.0.90~521^2~242

Ensure button-get works in any buffer

* lisp/button.el (button-get): Previously we assumed that button-get
  was called in the buffer containing the button.  In other buffers,
  button-get always returned nil.  Fix this by passing the relevant
  buffer from the marker.
