Shorten directory names in the path {path} and return the result. The tail, the file name, is kept as-is. The other components in the path are reduced to {len} letters in length. If {len} is omitted or smaller than 1 then 1 is used (single letters). Leading '' and '.' characters are kept. Examples: :echo pathshorten('/.vim/autoload/myfile.vim') /.v/a/myfile.vim ~ :echo pathshorten('/.vim/autoload/myfile.vim', 2) ~/.vi/au/myfile.vim ~ It doesn't matter if the path exists or not. Returns an empty string on error. Can also be used as a |method|: GetDirectories()->pathshorten()
