IndexOutOfBoundsException in Tag mode

[GoogleCodeExporter]

What steps will reproduce the problem?
Run java -jar daisydiff.jar a.html b.html --type=tag

What is the expected output? What do you see instead?
The expected output is any result.

Instead there is an exception

..java.lang.IndexOutOfBoundsException: There is no Atom with index 3
        at org.outerj.daisy.diff.tag.TagComparator.getAtom(Unknown Source)
        at org.outerj.daisy.diff.tag.TagDiffer.preProcess(Unknown Source)
        at org.outerj.daisy.diff.tag.TagDiffer.diff(Unknown Source)
        at org.outerj.daisy.diff.DaisyDiff.diffTag(Unknown Source)
        at org.outerj.daisy.diff.Main.main(Unknown Source)

Applies in DaisyDiff 1.0 and 1.1. Also notice that if the order of the 
input files is reversed, there is NO exception. The files themselves are 
really simple.

Bug fix
TagDiffer.java
line 185

Old:
while ((leftComparator.getAtom(temp) instanceof DelimiterAtom || 
(bridgelength-- > 0))
                        && temp < differences[i + 1].leftStart()) {

                    temp++;
                }
New:

while (temp < differences[i + 1].leftStart() && (leftComparator.getAtom(temp) 
instanceof DelimiterAtom || (bridgelength-- > 0)) ) {

                    temp++;
                }

Aha! Thanks for submitting this patch. If it is so simple and testcases finish 
successfully it will be committed to trunk.
