window for displaying another buffer in it. @code{get-lru-window} and

+@code{get-largest-window} (@pxref{Cyclic Window Ordering}) do not
+consider dedicated windows as candidates when their @var{dedicated}
+argument is non-@code{nil}. The behavior of @code{set-window-buffer}
(@pxref{Buffers and Windows}) with respect to dedicated windows is
slightly different, see below.
-When @code{delete-windows-on} (@pxref{Deleting Windows}) wants to
-delete a dedicated window and that window is the only window on its
-frame, it deletes the window's frame too, provided there are other
-frames left. @code{replace-buffer-in-windows} (@pxref{Switching
-Buffers}) tries to delete all dedicated windows showing its buffer
-argument. When such a window is the only window on its frame, that
-frame is deleted, provided there are other frames left. If there are
-no more frames left, some other buffer is displayed in the window, and
-the window is marked as non-dedicated.
-
-When you kill a buffer (@pxref{Killing Buffers}) displayed in a
-dedicated window, any such window usually gets deleted too, since
-@code{kill-buffer} calls @code{replace-buffer-in-windows} for cleaning
-up windows. Burying a buffer (@pxref{The Buffer List}) deletes the
-selected window if it is dedicated to that buffer. If, however, that
-window is the only window on its frame, @code{bury-buffer} displays
-another buffer in it and iconifies the frame.
+ Functions supposed to remove a buffer from a window or a window from
+a frame can behave specially when a window they operate on is dedicated.
+We will distinguish three basic cases, namely where (1) the window is
+not the only window on its frame, (2) the window is the only window on
+its frame but there are other frames on the same terminal left, and (3)
+the window is the only window on the only frame on the same terminal.
+
+ In particular, @code{delete-windows-on} (@pxref{Deleting Windows})
+handles case (2) by deleting the associated frame and case (3) by
+showing another buffer in that frame's only window. The function
+@code{replace-buffer-in-windows} (@pxref{Buffers and Windows}) which is
+called when a buffer gets killed, deletes the window in case (1) and
+behaves like @code{delete-windows-on} otherwise.
+
+ When @code{bury-buffer} (@pxref{The Buffer List}) operates on the
+selected window (which shows the buffer that shall be buried), it
+handles case (2) by calling @code{frame-auto-hide-function}
+(@pxref{Quitting Windows}) to deal with the selected frame. The other
+two cases are handled as with @code{replace-buffer-in-windows}.

+ * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
+ between bpos_covered and bpos_max. This fixes cursor display when
+ several display strings follow each other.
+
+ * .gdbinit (pgx): If the glyph's object is a string, display the
+ pointer to string data, rather than the value of the string object
+ itself (which barfs under CHECK_LISP_OBJECT_TYPE).
+
+ * indent.c (Fvertical_motion): If the starting position is covered
+ by a display string, return to one position before that, to avoid
+ overshooting it inside move_it_to. (Bug#12930)
