Delete messy example

Fixes https://github.com/ietf-wg-jsonpath/draft-ietf-jsonpath-base/issues/274

Do we intend to replace this with anything? What is its purpose in being here?

[timbray]

The N-1 line also illustrates the point so I think it's probably OK to leave it?

Sorry, I didn't pay attention. The purpose of this example was to show that escaped characters are normalized into their actual equivalents (unless there is a reason not to do so).

The messiness is a workaround for xml2rfc bugs. I'm confident we can get these bugs fixed before this is published; otherwise we might indeed want to skip this example.

[glyn]

Why doesn't the $["\u0061"] example already show that an escaped character is normalised into its actual equivalent ("a")?

[cabo]

It does. Many implementers will however think that this only applies to 95-ASCII characters (there is no reason for thinking that, but it is a highly likely misunderstanding).
