Opening Links in the Same Window

[John Beales <john johnbeales com>]

Hi,

I'm fairly new to linux, and I just stumbled across Epiphany today.   
It looks like a pretty good browser, and well suited to my application.
I'm having a problem though.  I'm sending it URLs to open from the  
shell using the -remote switch.  Like this:  epiphany -remote "openURL 
(http://www.google.com)"
I know it's undocumented, but it works fine.  I assume it's inherited  
from the mozilla/gecko code.  However, I want these links to open in  
the same window, and same tab, that is already open.  That is, I only  
ever want to have 1 window open, with 1 tab in it, and when I send a  
URL to be opened it should open in that existing tab.  In Firefox I  
can do this by going into about:config and setting both  
browser.link.open_external = 1 and browser.link.open_newwindow = 1   
Since these options are both available in Epiphany I had expected it  
to work.  However, it doesn't.  New websites are opened in new windows.
Does anyone know if there's a way to open links from external sources  
in the same window?
Thanks,

John
