This is good idea: I personally have a few `exec` calls in my zshrc (basically they do two things: launch shell in dtach if it is not already in tmux/dtach/screen and use `hilite` program if it was not already used), but by doing this I loose the possibility to use `zsh -ic`. Presence of the variable which contains `-c` argument will fix this problem.
