        the backspace_deletes_character PangoLogAttr.

        * gtk/gtktextbuffer.[ch] gtk/gtk.symbols (gtk_text_buffer_backspace):
        Move backspace logic from GtkTextView to here, check
        backspace_deletes_char.

        * gtk/gtktextview.c: Use gtk_text_buffer_backspace().

/**
* gtk_text_buffer_backspace:
* @buffer: a #GtkTextBuffer
* @iter: a position in @buffer
* @interactive: whether the deletion is caused by user interaction
* @default_editable: whether the buffer is editable by default
*
* Performs the appropriate action as if the user hit the delete
* key with the cursor at the position specified by @iter. In the
* normal case a single character will be deleted, but when
* combining accents are involved, more than one character can
* be deleted, and when precomposed character and accent combinations,
* less than one character will be deleted.
*
* @iter must be at a cursor position.
*
* Return value: %TRUE if tbe buffer was modified
* Since: 2.6
