 * Caja uses to address the desktop via the 'x-caja-desktop:///' URI.

 * In this case, we prefer the vfs->path member wich is just a decomposition of the
 * URI, and does not try to interpret it.
 *
 * *********************************************************************************
 * Extract from RFC 2396:
 *
 * 2.4.3. Excluded US-ASCII Characters
 *
 * Although they are disallowed within the URI syntax, we include here a
 * description of those US-ASCII characters that have been excluded and
 * the reasons for their exclusion.
 *
 * The control characters in the US-ASCII coded character set are not
 * used within a URI, both because they are non-printable and because
 * they are likely to be misinterpreted by some control mechanisms.
 *
 * control = <US-ASCII coded characters 00-1F and 7F hexadecimal>
 *
 * The space character is excluded because significant spaces may
 * disappear and insignificant spaces may be introduced when URI are
 * transcribed or typeset or subjected to the treatment of word-
 * processing programs. Whitespace is also used to delimit URI in many
 * contexts.
 *
 * space = <US-ASCII coded character 20 hexadecimal>
 *
 * The angle-bracket "<" and ">" and double-quote (") characters are
 * excluded because they are often used as the delimiters around URI in
 * text documents and protocol fields. The character "#" is excluded
 * because it is used to delimit a URI from a fragment identifier in URI
 * references (Section 4). The percent character "%" is excluded because
 * it is used for the encoding of escaped characters.
 *
 * delims = "<" | ">" | "#" | "%" | <">
 *
 * Other characters are excluded because gateways and other transport
 * agents are known to sometimes modify such characters, or they are
 * used as delimiters.
 *
 * unwise = "{" | "}" | "|" | "\" | "^" | "[" | "]" | "`"
 *
 * Data corresponding to excluded characters must be escaped in order to
 * be properly represented within a URI.
 *
 * pwi 2011-01-04:
 * It results from the above excerpt that:
 * - as double quotes are not valid character in URI, they have to be
 *   escaped as %22, and so Caja does
 * - but simple quotes are not forbidden, and so have not to be
 *   escaped, and so Caja does not escape them
 *
 * As a result, we may have valid, non-escaped, simple quotes in an URI.
