[ESS-bugs] Re: [ESS] Solved - no gnuclient in linux

[Martin Maechler]

This seems two bugs that we should fix:

1) The documentation mentions "gnuclient" only for windows,
   but AFAICS it is also needed (and used) for Xemacs on
   non-windows.

2) Can we find out if the "-q" switch can safely be dropped,
   or is it needed when using  gnuclient on windows
   (for GNU emacs and / or Xemacs, there) ?

It would be great if this could be resolved soon.
I definitely would like to release ESS 5.2.7  before mid of April!
   
(OTOH, semester and teaching has started, and I am pretty busy.)
