| # \] is not a valid escape for ] in set glob expression. |
| # Glob sets have no escaping at all: |
| # ] can be in a set if it is the first char: []abc], |
| # dash can be in a set if it is first or last: [abc-], |
| # [ and \ need no protections at all: [a[b\c] is a valid set of 5 chars. |
| # |
| # bash-4.3.43 misinterprets [a\]] as "set of 'a' or ']'". |
| # Correct interpretation is "set of 'a' or '\', followed by ']'". |

| echo Nothing:"${x#[a\]]}" |
