The offender was `print -P`, where `-P` does [prompt expansion](http://zsh.sourceforge.net/Doc/Release/Prompt-Expansion.html#Prompt-Expansion). I took the freedom to also change a few things: Move the `add-zsh-hook precmd` up, add `prompt_magicmace_` prefix to all function names, add `COLOR_` prefix to all color global variables, and move assignment to `PROMPT` to `prompt_magicmace_setup`. Fixes #70, Closes #81
