The description says it will remove the trailing slash from a home path (relative path starting with tilde).

A simple

 @Test void returnsHomeWithTrailingSlash_forHomeWithTrailingSlash() {
 assertThat(FilenameUtils.getFullPathNoEndSeparator("~/")).isEqualTo("~/");
 }

proves otherwise.

This fixes the description accordingly. NB: this behaviour has been existent since 2.4, where i discovered it.
