strlcpy() will always null terminate the string.

    The code should already guarantee this as the last bytes are already
    NULs and the string lengths were restricted before being stored in
    hc.  Removing the '-1' becomes necessary so strlcpy() doesn't
    lose the last character of a maximum-length string.
