I'm trying to make my fish_prompt function intelligent enough to handle any
width.
When wide enough, I'm outputting the current directory path and the Git
branch if I'm in a Git repo.
If the window too narrow to display all of that on one line, I display them
on two lines.
If the directory won't fit, I output the result of prompt_pwd instead.
Below 20 columns I want to just display a fish icon.
That's why I need to be able to detect whether the window is less than 20
columns.
I use tmux and sometimes have narrow panes from lots of splitting.
Typically I won't have panes that narrow, but when I do I want to handle it
and not just have a ">" prompt.
