bug finding a max with letter-spacing

[usrlocalben]

If you have negative letter-spacing, then container width() can be zero as the loop starts to find a max to bsearch from. In this case, it will exit early since it compares it against the (uninitialized) variable 'width' . The comments say that this is to "prevent an infinite loop." I'm not sure what testcase might cause that, but it appears that this code is unnecessary. If I set realWidth to container.width() and remove the infinite loop stuff then it works fine.
