In Gnu Emacs 17.57, on both Pyramid and Sun, we kept seeing "OOPS" on
the screen whenever there was a line wrap on a terminal with the "xn"
property in termcap. The problem turns out to be in cm.c. Look for
"fail:". Change "return c" to "return BIG". This is in the routine
to do cursor positioning by up and down commands (i.e. not direct
cursor positioning). There is a case in which we can get to this code
with c not set to anything. At this point in the cost, we always want
a large cost to be returned, so it is simplest just to return BIG,
instead of worrying about what is in c.
dodelta:
if (c == BIG) { /* caint get thar from here */
fail:
if (doit)
printf ("OOPS");
/* RUTGERS was return c - that fails in case goto fail, since c is not set */
return BIG;

This bug is fixed in 17.58.
