I'm sure there isn't a single "right" answer to this question, but if
transferring Pascal source to a system that enforces short lines (e.g.

One possibility is obviously to break after the rightmost space, but is
it valid to break after e.g. . (if not followed by a digit), ^ and
possibly others?
Syntax errors are acceptable. Truncation isn't.
Is it valid...? Yes.
The compiler largely ignores line endings and line breaks (since they're
inserted mainly for formatting, not syntax purposes).
One exception is string constants, so your parser will have to track the
"'" character and ensure a corresponding later match within the short
line, or else insert a forced concatenation.

Also single-line comments are obviously broken by wrap, i.e. preceded by //
I can cope without trying to parse for strings etc., since I think that
in all cases compiling a broken string would result in a syntax error.
