[PATCH] ash: remove defunct control character to save a few bytes

[Ron Yorston]

Commit 549deab5a (ash: move parse-time quote flag detection to
run-time) did away with the need to distinguish between backquotes
inside and outside quotes.  This left a gap among the control
characters used in argument strings.  Removing this gap saves a
few bytes.
