Yes.
You can add a filter, see (info "(org) Advanced configuration")
The line breaks come _after_ the code is processed. So you need to make
the line breaks happen before you know can replace them. Try:
#+BEGIN_SRC emacs-lisp
(defun org-export-ascii-filter-code (text back-end info)
"Replace `\\n' with `\\' in ascii code."
(if (eq back-end 'ascii)
(replace-regexp-in-string
"\n" "\\\n"
(org-babel-chomp
(org-export-string-as text 'ascii t))
nil t)
text))
(add-to-list 'org-export-filter-code-functions
'org-export-ascii-filter-code)
#+END_SRC
with ascii export.
When I run this on your example, I get only one line break, but it is
preceeded by a backslash.
Naturally, you will need to adapt this up for other backends as a single
backslash might not be what is wanted.
HTH,
Chuck
