108 * anything that the shell would. Both single and double quotes are handled,

111 * Shell quoting rules are a bit strange. Single quotes preserve the literal
112 * string exactly. Escape sequences are not allowed; not even <tt>\\'</tt> --
113 * if you want a <tt>'</tt> in the quoted text, you have to do something like
114 * <tt>'foo'\\''bar'</tt>. Double quotes allow <tt>$</tt>, <tt>`</tt>,
115 * <tt>"</tt>, <tt>\\</tt>, and newline to be escaped with backslash.
116 * Otherwise double quotes preserve things literally.
