If the position of a window's cached point is deleted, use buffer point instead src/ChangeLog addition: 2014-06-17 Aidan Kehoe <kehoea@parhasard.net> * extents.h: * window.c: * window.c (unshow_buffer): * window.c (Fset_window_buffer): Use extents, rather than markers, for the window buffer point cache, so that when the text containing that window buffer point is deleted, the window display code uses the buffer's actual point instead of the position that the marker had been moved to. Fixes Michael Heinrich's problem of http://mid.gmane.org/6zr42uxtf5.fsf@elektra.science-computing.de , introduced by Ben's patch of https://bitbucket.org/xemacs/xemacs/commits/047d37eb70d70f43803 .
