There is no easy way to diff these files against the source as the source was split into new files.

Another example is unrelated to a note:

While he was advancing from the Hellespont to Lysimacheia a splendid great altar presented itself to his view, which he was told had been built either by the Argonauts on their way to Colchis, or by the Ach&aelig;ans who besieged Troy, for which reason the people in the neighborhood still called it Argos, either by a corruption of the name of the ship <title>Argo,</title>

As his army <note resp="HW" place="marg" anchored="yes">Y.R. 87</note> was superior in number to that of Sulla before, it now became much more so by these re&euml;nforcements.

Note in all these examples, the text that goes missing starts with the word "from".

Was there some kind of pattern editor or other transformation that operated on this word?
