Start small. If it works well we can increase usage bit by bit as time passes. Note that we keep using "0" to represent "no specific line" because changing to `Option<LineNumber>` everywhere is much bigger and noisier change. That can be done later if wanted.

I've done some additional verification and code cleanup and am happy with how this works and looks. Ready for review! |

My main motivation for doing this is to get rid of the
+ 1I otherwise have to add in #150201 on this line:But I think this is a nice general improvement by itself.
Note that we keep using "0" to represent "no specific line" because changing to
Option<LineNumber>everywhere is a very noisy and significant change. That can be changed later if wanted, but let's not do it now.
