PySelection has a 'selectCompleteLine' method that may be what you want...

Eventually I replace this paragraph with a reformatted paragraph. In

Actually, I think you could use the PySelection.deleteLine approach (it
checks the offset of the next line to see what it should delete -- if
there's a 'next' line).

It is possible that this is not true, for example by using a Windows

Maybe, I'm not really sure about this one...

In any case, I can use the IDocument method getLineDelimiter() to get

Yeah, probably could be done...

Oops... Well, yes, Eclipse has one representation for the gui and one for
the internal API.
