Description of Problem:
The 'gedit' command will return right away if
there is already an existing gedit session.  If
gedit is being used as $EDITOR, this confuses
programs like svn and cvs which wait for the
editor program to return as a cue that the user
has finished editing the commit messages.

Steps to reproduce the problem:
1. Start gedit
2. set $EDITOR to 'gedit'
3. Run a command like 'svn commit'

Actual Results:
gedit connects to the existing session and returns
right away.

Expected Results:
gedit wouldn't return until the user closed the
window.

How often does this happen? 
always

Additional Information:
something like a '--new-session' option would
probably be enough for this to not be a problem. 
Personally, I would prefer if --new-session and
--new-window were the defaults.  Especially when
you have several viewports/desktops, it is pain
when a command like 'gedit blah.txt' steals the
gedit window off a different viewport/desktop.
