Shorten directory names in the path {expr} and return the result. The tail, the file name, is kept as-is. The other components in the path are reduced to single letters. Leading '' and '.' characters are kept. Example: :echo pathshorten('/.vim/autoload/myfile.vim') ~/.v/a/myfile.vim ~ It doesn't matter if the path exists or not. Can also be used as a |method|: GetDirectories()->pathshorten()
