I wanted to commit some more stuff for 2020. Better late than never,
right? The most significant change is probably in fish_prompt.fish.
I fixed an edge case where the directory in question could be the
same as the user's username.
The desktop directory is used for desktop-related things that may be
useful outside of bspwm (such as caps lock functioning as ctrl +
escape). Whether or not this is needed is questionable, but it is an
option for now.
It may be better to further split these directories and avoid the
generic word "desktop" altogether.
