This change allows leading zeros in parameters. I.e. it will accept
ESC [032m
as if it wereESC [32m
.This is mostly to support https://github.com/aybabtme/rgbterm which uses the sequence
ESC [0;00m
to reset the terminal colors to default:https://github.com/aybabtme/rgbterm/blob/cc83f3b3ce5911279513a46d6d3316d67bedaa54/rgbterm.go#L36
Really, the change could just as easily be made in rgbterm. But it seems like most terminals support having that leading zero (since rgbterm works in them), so it's likely that leading zeros would show up in other places like other colorizing implementations or people's scripts.
