-// ReplaceTilde builds a middleware which substitutes a leading '~' in the request path.

-// It makes the alteration to a copy of the request which is then passed into the
-// wrapped Handler. This way middlewares outside of this one inspecting the request
-// afterwards will see the original URL.
-//
-// Typically the replacement should end with a "/", so that the ~ ends up mapping to a
-// particular directory on the filesystem. For instance with a replacement string of
-// "users/", "domain.com/~jim/index.gmi" maps to "domain.com/users/jim/index.gmi".
