It's not ANSI. It's bash. Specifically, bash allows \e as a synonym for \033 when expanding PS1, and inside $'...' quotes, and in readline key sequence definitions, and in arguments to echo with the -e option. It also allows \e in the printf format argument, though I don't see this mentioned in the documentation.
