ah, but see, i don't have to guess.

hg help status has:
    The codes used to show the status of files are:
    M = modified
    A = added
    R = removed
    C = clean
    ! = missing (deleted by non-hg command, but still tracked)
    ? = not tracked
    I = ignored
      = origin of the previous file listed as A (added)
