IM I-375: "Normally ... the text automatically wraps around ... .  A new line
also begins where explicitly specified by a Return character in the text."
(See also I-378, last para.)

That is, "normally" there are no terminators at the end of each line; this
would be the case for, e.g., most dialog box static text items -- TextEdit
takes care of formatting the text with respect to lines, and calculates the
contents of the lineStarts array based on the width of the destination
rectangle.  For line-oriented text, e.g., most program source code, there
would be a CR at the end of each line of text.

> Where does it say whether the LineStarts are 0- or 1-based?

IM I-377: "lineStarts: ARRAY[0..16000] OF INTEGER" (see also I-379, last
para.)
