"begin_src R :session" opens R session when file first visited

[William Denton]

A question for R users:

I run Org from the source tree, and recently (a couple of weeks ago or so) 
something new started happening with my Org files with R source blocks:  when I 
open one up, an R session automatically starts, without me doing anything.

For example:

    #+BEGIN_SRC R :session foo
    1
    #+END_SRC

If I have that in a file, restart Emacs and visit the file, an unnamed R session 
begins right away (without a C-c C-c).  I changed "R" to "python" and 
restarted, and all was normal (i.e., nothing happened) but when I edited it to 
say "R" again, the session began as soon as I put the letter in!

I haven't changed anything in my configuration related to Org or R, and I can't 
see why this is happening.  Looking at recent commits I saw all the R 
async work, and changes made to session-related code, but I can't tell if 
there's any connection.

Are any other R users seeing this?  I admit I haven't done a full investigation, 
but I thought I'd ask.


Thanks,

Bill
