pathcomplete: remove ambiguous entries for sole completion on a directory Previously, directories were added with the trailing slash and, if there was only one completion, then another ambiguous entry was created using '.', as follows: $ hg rm mer<TAB> mercurial/./ mercurial// This was added in fa6d5c62f3bd (though, some logic existed before that) to work around bash completion adding a space after the sole entry because we treated directories and files the same. We no longer do that now so we remove this unneeded code. Tests have been updated to match this new behavior.
