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.
The null string (NULL) and the empty string ("") are not the same thing.
If nullglob is set, the non-matching pattern expands to the null string,
which is removed by word splitting.
