You may misunderstand the intent.
The "use-a-shell" option would normally imply that a shell sill be used
to parse the command line, thus you must always worry about
meta-characters in this case. If exim had the 'shquote' variable
expansion qualifier then ensuring the sanctity of values to be passed on
a shell command line would be relativley easy.
However, it's possible to optimize out the shell (and thus gain a tiny
performance increase) if there are no metacharacters in the current
command. This is what make does.
