Subject: bug#12170: save-excursion fails boundary case with recenter
Date: Thu, 9 Aug 2012 21:23:04 -0400	[thread overview]
Message-ID: <000001cd7696$b0e93d60$12bbb820$@com> (raw)

[-- Attachment #1: Type: text/plain, Size: 427 bytes --]

Running GNU Emacs 24.1.1 (i386-mingw-nt6.1.7601) of 2012-06-10 on MARVIN
under Windows 7.

 

Define:

 

                (defun f (n) (save-excursion (forward-line (- n)) (recenter
0)))

 

Let H be the window height in lines, and suppose that point is positioned at
the beginning of line L > H.

 

Despite 'save-excursion', (f K) moves point if K = H.  It leaves point
unchanged for any other value of K, 0 <= K < L.
