not too sure about ash but you get less chars with:
print "${new% }"
another way showing off some aspects of modern shells
but still a bit longish...
% stephan@labaule (/home/stephan) %
% cat rev.sh
#!/bin/ksh93
function rev
{
nameref s=$1; typeset a=( $s ); integer n=${#a[*]} i; s=; n=n-1
for i in {$n..0}; do s+="${a[i]} "; done; s=${s%?}
}
s=" one two three four "
rev s
print "[$s]"
% stephan@labaule (/home/stephan) %
% ksh93 rev.sh
[four three two one]
enjoy ;)

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
