In a shell, running a command like the following causes a problem with dirtrack-mode: echo 'Coltons-MacBook-Pro:/Users/coltongoates/software-dev/$' After running this command, dirtrack thinks I changed to a different directory based on the output, and it sets the default-directory variable to the output of the echo command. Thus, the actual working directory and shell directory are out of sync.
