Subject: 23.3; Hl-Line mode
Date: Tue, 22 Mar 2011 23:33:49 +0100

I observed the following with Emacs 23.3:

Turn Global-Hl-Line mode on, and open any text file. Then do M-x occur Ret, some word Ret, so as to get two windows, one with the text file, the other with the occur buffer. Now by default, the variable HL-Line-Sticky-Flag is set to non-nil, which, according to the documentation of that variable, means that the current line is highlighted in all windows. However, this seems not to work: Switching between the two windows, you see only the current line in the selected window to be highlighted.

This becomes a problem, in particular, when one does M-x next-error-follow-minor-mode in the window with the occur buffer. After this, moving the down or up arrow key in the occur buffer window leads, as it should, the cursor in the other window to move to the corresponding line there, but as that line, even though it becomes the "current line", does not become highlighted, there is some visibility problem, which would disappear would HL-Line-Sticky-Flag being set to non-nil work as advertised.

hl-line-sticky-flag is not intended to affect global-hl-line-mode, only
the local mode.  However, it's simple enough to add a similar mechanism
for the global mode (global-hl-line-sticky-flag), so I've done that.
