Expand the full view directory in prompt

[hotoolong]

Description

Allows you to set the range in which the full directory is displayed in the prompt.

For example
If I was working in

/Users/hotoolong/.ghq/github.com/hotoolong/translate.nvim

By default, the display is as follows. (For my settings)

~/.g/g/h/translate.nvim (master|✔) $ 

If you set the full directory to display to 3,

set -g fish_prompt_dir_full_name_range 3

It appears as follows

~/.g/github.com/hotoolong/translate.nvim (master|✔) $

The following is similar issue.
#3566

TODOs:

• Changes to fish usage are reflected in user documentation/manpages.
• Tests have been added for regressions fixed
• User-visible changes noted in CHANGELOG.rst

Sorry, I don't think there's a need for multiple variables here, use $fish_prompt_pwd_dir_length or use your own function if you want more complicated behavior.

Thanks for the quick reply. I was hoping that some way of displaying the parent directory from the current directory would be added.
It's a shame this time, but I'll try to deal with it by overwriting the function.
