suggestion(non-blocking): Since tw_home_relative_wd is now only used inside of the tw_get_displayed_wd function, let's move the variable inside and not pass it as a param anymore

@reobin quick question about these. Since we're no longer sending tw_home_relative_wd as a param, do you feel strongly about no longer sending params to this function in general? as in changing this block to

  local tw_home_relative_wd="$(tw_get_home_relative_wd)"
  local tw_git_branch="$tw_prompt_data[tw_git_branch]"
  local tw_git_home="$tw_prompt_data[tw_git_home]"

Since those aren't used in any other place in tw_redraw() except as params for tw_get_displayed_wd() it almost makes sense to me that they are just set there but I'm not as versed in zsh as you are so I wanted to make sure this made sense to you as well before I did that.

You are right! Good catch

While we're at it, there are some other cleanups we can do in the same section.

The tw_get_home_relative_wd function is not very useful. We can merge that into tw_get_displayed_wd.

Here's my suggestion for a new tw_get_displayed_wd:

tw_get_displayed_wd() {
  local tw_git_branch=$tw_prompt_data[tw_git_branch]
  local tw_git_home=$tw_prompt_data[tw_git_home]

  local tw_home_relative_wd="%~"
  local tw_git_relative_wd="$tw_git_home%c"

  local tw_displayed_wd="$tw_git_relative_wd"

  # The pure layout defaults to home relative working directory, but allows customization
  if [[ "$TYPEWRITTEN_PROMPT_LAYOUT" = "pure" && "$TYPEWRITTEN_RELATIVE_PATH" = "" ]]; then
    tw_displayed_wd=$tw_home_relative_wd
  fi;

  if [[ "$TYPEWRITTEN_RELATIVE_PATH" = "home" ]]; then
    tw_displayed_wd=$tw_home_relative_wd
  fi;

  if [[ "$TYPEWRITTEN_RELATIVE_PATH" = "adaptive" ]]; then
    if [[ "$tw_git_branch" = "" ]]; then
      tw_displayed_wd=$tw_home_relative_wd
    fi;
  fi;

  echo "%F{$tw_current_directory_color}$tw_displayed_wd"
}

Mainly what changes here is that we only make 1 call to the color that the current directory should have, and that's on the return statement (echo).

Awesome, changes pushed up in c087e32
