How does one embed a literal ctrl-A or ctrl-B in the prompt? I
haven't found any readline documentation that explains the use of
"start of header" or "start of text".
In zsh, should an extra digit immediately following \001 be treated as
a "glitch" width?
I'm also leaning to the opinion that \001 and \002 should only be
recognized when PROMPT_PERCENT is unset.
