You may use the following script in your my-init-texmacs.scm:

------------------------------------------------------------
(define (string-space-at? s i) (== #\space (string-ref s i)))
(define (tree-leaf? t) (== "" (tree-get-label t)))
(define (tree-func? t s) (== s (tree-get-label t)))
(define (near-space?/leaf t1 i)
(let ((s (tree->object t1)))
(or (and (< 0 i)
(string-space-at? s (1- i)))
(and (< i (string-length s))
(string-space-at? s i)))))

(define (near-space?/after p1)
(and-let* ((t2 (tm-subtree (cDr p1)))
((tree-func? t2 "concat"))
(i (cAr p1))
((< (1+ i) (tree-arity t2)))
(next-t (tree-ref t2 (1+ i)))
((tree-leaf? next-t))
((string-space-at? (tree->string next-t) 0)))))

(define (near-space?)
(let* ((p (the-path))
(p1 (cDr p))
(i (cAr p))
(t1 (tm-subtree p1)))
(cond ((tree-leaf? t1) (near-space?/leaf t1 i))
((== i 1) (near-space?/after p1))
(else #f))))

(define (smart-space)
(if (not (near-space?)) (insert-string " ")))
(kbd-map in-text? ("space" (smart-space)))
------------------------------------------------------------

Note: These scripts use the new syntax for keymap definition
introduced in TeXmacs-1.0.1.4.
