In light of CCL's interpretation of the standard, can you suggest a
terse way to get a list of all files with a pathname-type of "txt" in a
directory tree rooted at e.g. #p"foo/" where some entries under foo/
might be symlinks to directories outside of foo/? I don't mind using
something implementation-specific if it does the job.
