Actually, the problem seems to be in the `insert-directory-wildcard-in-dir-p' function
which wrongly splits "c:/tmp/dir*/*.txt" in ("c:/tmp/" . "dir*/*.txt") instead of
("c:/tmp/dir*/" . "*.txt")

Forget this (wrong) diagnostic.

The culprit is actually

(let ((default-directory "c:/tmp/"))

(eshell-extended-glob "dir*/*.txt"))

"dir*/*.txt"

which fails to expand the wildcards (when `file-expand-wildcards' succeeds).
