Modified Files:
src/bin/sh: show.c
Log Message:
DEBUG mode only change. When pretty-printing a word from a parse
tree, don't display a CTLESC which is there only to protect a CTL*
char (a data char that happens to have the same value). No actual
CTL* chars are printed as data, so no escaping is needed to protect
data which just happens to look the same. Dropping this avoids the
possibility of confusion/ambiguity in what the word actually contains.
NFC for any normal shell build (very little of this file gets compiled there)
