Using regex to allow rendering notes with an indent, for example:

{{< note >}}
If the last element of the path is a substring of the
last element in request path, it is not a match (for example:
`/foo/bar` matches`/foo/bar/baz`, but does not match `/foo/barbaz`).
{{< /note >}}

After changin to hugo 0.70 trim seems to be not working.
