* anything that the shell would. Both single and double quotes are handled,
* as are escapes including escaped newlines.
*
* Shell quoting rules are a bit strange. Single quotes preserve the literal
* string exactly. Escape sequences are not allowed; not even <tt>\\'</tt> --
* if you want a <tt>'</tt> in the quoted text, you have to do something like
* <tt>'foo'\\''bar'</tt>. Double quotes allow <tt>$</tt>, <tt>`</tt>,
* <tt>"</tt>, <tt>\\</tt>, and newline to be escaped with backslash.
* Otherwise double quotes preserve things literally.
