Remove invalid docs regarding parsing PathBuf (#230)

Browse Source 
This paragraph is no longer valid since v1.0!

Also, the example code still compiles fine and this may easily introduce
a security vulnerability for the user.

@ -259,24 +259,6 @@ Specific values can be retrieved with [`Path::get()`][pathget].
For this example for path '/a/1/2/', values v1 and v2 will resolve to "1" and "2".
It is possible to create a `PathBuf` from a tail path parameter. The returned `PathBuf` is
percent-decoded. If a segment is equal to "..", the previous segment (if
any) is skipped.
For security purposes, if a segment meets any of the following conditions,
an `Err` is returned indicating the condition met:
* Decoded segment starts with any of: `.` (except `..`), `*`
* Decoded segment ends with any of: `:`, `>`, `<`
* Decoded segment contains any of: `/`
* On Windows, decoded segment contains any of: '\'
* Percent-encoding results in invalid UTF8.
As a result of these conditions, a `PathBuf` parsed from request path parameter is
safe to interpolate within, or use as a suffix of, a path without additional checks.
