Along with following sed(1) line it's intended to work around `echo'
builtin from dash acting like printf(1).
s/\\([[:digit:]]+)/\\0\1/g
Rather than calling sed(1) for every `echo' I've descided to place it
only where it's needed as an optimization, i.e. only when
`string-to-bytes' maybe used.
BTW, bash at least on FreeBSD treats only \0XXX (not \XXX) sequences as
character codes. I wonder if a command like `windows' ever worked on it,
e.g. with window titles in japanese, not displaying smth like
> windows
0+\343\203\213\343\202\263\343\203\213\343\202\263\345\213\225\347\224\273(9)

Nah, it turns out I've missed the case when there are *quoted*
doublequotes at the end of line, e.g.
