Analysis of patterns at the very start and end of lines, per line type

[Jorge_Stolfi]

I think there is almost no missunderstanding with potential existing spaces, as the analysis is just the initial word and the final word of the line.

Wrong spaces would not affect the word-initial probabilities at the start of body lines, but would affect the word-initial probabilities for other words of the line.  Aren't the latter being used as reference, to declare the former anomalous?

All the best, --jorge
