Today, a user in the #bash IRC channel of libera.chat, misunderstood how nullglob is supposed to work because is documented incorrectly in the man page:
'nullglob'
If set, Bash allows filename patterns which match no files to
expand to a null string, rather than themselves.
globs expand to nothing if there are no matches with nullglob set, not
to the null/empty string.
