If you are referring to the "xdiff/xdiffi.c:line 261" one (which
I did not say if I looked at it or not), I think there is
nothing to fix there, either. In front of itt is a big fat loop
controlled with:
for (ec = 1;; ec++) {
...
}
and only exits from there are returns. Two "break" appear but
they are breaking out of nested inner loops and would not escape
this outermost loop.
