``prompt_pwd`` is a function to print the current working directory in a way suitable for prompts. It will replace the home directory with "~" and shorten every path component but the last to a default of one character.
To change the number of characters per path component, pass ``--dir-length=`` or set ``$fish_prompt_pwd_dir_length`` to the number of characters. Setting it to 0 or an invalid value will disable shortening entirely.
