I suspect that, at one point in time, this may have been manually
inlined for performance.  Not that I care, just that it's likely.  Might
be good to compare runs of x11perf -wline{10,100,500}.

Of course, in that sense, we're already losing relative to X11R4,
because we're using malloc instead of alloca.
