Per <https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=bf079e19f50d64aa5e05b5e17ec29afab9aabb20>: * this was set by bash 2.0 (1996-12) (implemented in glibc b07c5668f672125074dd5b0b658145e1544120be) * it's no longer set by bash 2.01 (1997-06) because it was bad * glibc disabled this with no way to enable it in 2001-08 (518a0dd201c48a5c15d73c1919c304a9f8f5e3c1) * glibc removed it in 2017 bf079e19f50d64aa5e05b5e17ec29afab9aabb20 So this was experienced by people for 5 months at best, and could remotely be experienced for 3 years (if you somehow wanted this bad behaviour and added it into your shell), over 20 years ago. No modern reader (or, frankly, non-modern reader) has ever used this, or could use it, really. Link to the removal note for completeness only.
