Allows the length of each shortened path component to be customized by setting the `fish_prompt_pwd_dir_length` variable to the number of characters to include (plus a leading dot because that's special). Maintains the default behavior of shortening path components to just one character. You can also set `fish_prompt_pwd_dir_length` to an empty or invalid value or 0 to disable shortening completely.
