Cool things that make zsh appealing

• Filename correction during completion

• if dir1/x exists and dir2 exists, then "dir/x<TAB>" completes to dir1/x

• if name1 is a file and name2 is a directory with files in it, "name/<TAB>" completes to "name2/"

• Better ctrl-R behaviour

• alerts you if your ctrl-R is failing

• completes it right on the prompt line while showing you what you're searching for below
