Can you confirm that this fixes your problem?

(in-package :swank)

(defun make-compound-prefix-matcher (delimiter &key (test #'char=))
  "Returns a matching function that takes a `prefix' and a
`target' string and which returns T if `prefix' is a
compound-prefix of `target', and otherwise NIL.

Viewing each of `prefix' and `target' as a series of substrings
delimited by DELIMITER, if each substring of `prefix' is a prefix
of the corresponding substring in `target' then we call `prefix'
a compound-prefix of `target'.

DELIMITER may be a character, or a list of characters."
  (let ((delimiters (etypecase delimiter
     (character (list delimiter))
     (cons      (assert (every #'characterp delimiter))
        delimiter))))
    (lambda (prefix target)
      (declare (type simple-string prefix target))
      (loop with tpos = 0
   for ch across prefix
   always (and (< tpos (length target))
(let ((delimiter (car (member ch delimiters :test test))))
 (if delimiter
     (setf tpos (position delimiter target :start tpos))
     (funcall test ch (aref target tpos)))))
   do (incf tpos)))))
