    Fix core in multi-line selection on OpenBSD
    
    OpenBSD 5.3 amd64 release version with the most current st
    version from git, crash and dump core when selecting multiple
    lines whith the cursor. This happens, because on line 964
    of st.c (gp-1)->mode is accessed, although gp is still
    pointing at the beginning of the array term.line[y] (see
    line 939 for initialization of gp).
