capital letter bounding boxes not computed correctly by gnuplot

It seems that the text bounds computed by gnuplot are ignoring capital
letters. I have no idea where the exact problem is, but using capital
letters anywhere shows the bug: put a long strings of caps as an x label,
or any label. For now I've added a hack to try and fudge the bounding box
for the legend but there's no clean way to do it w/o querying X.
