It seems like if nothing else that should be

   (setf (vim::buffer vim::*vim-buf-stream*) (vim:current-buffer))

Was that a typo in your email or in your original code?

Second, the safe-eval I have in my repository says

"  (defun safe-eval (form from-ex)                                          \n"
"    \"evaluates a form, reporting any errors\"                             \n"
"    (handler-case                                                          \n"
"      (if from-ex                                                          \n"
"        (progn                                                             \n"
"          (when (stringp form)                                             \n"
"            (cl:setq form (read-from-string form)))                        \n"
"          (eval form)                                                      \n"
"          (fresh-line *standard-output*))                                  \n"
"        (let ((*standard-output* *vim-buf-stream*)                         \n"
"              (*error-output* *vim-buf-stream*))                           \n"
"          (eval form)))                                                    \n"
"      (error (cnd)                                                         \n"
"        (format t \"ERROR: ~a~%\" cnd))))                                  \n"

which binds *standard-output* only if from-ex is false, but as near as
I can tell from-ex would always be true.  Try binding
*standard-output* to *vim-buf-stream* yourself, maybe?
