IME it varies depending on which compiler you use; some report the line
where the ereport is. So I'm doubtful that there's going to be much we
can do about it. Probably this behavior is bound up with macro expansion
vs. just when __LINE__ is expanded.

(No, I won't hold still for a coding requirement that all ereport calls
be smashed onto a single line ;-))

Personally, my habit is to set the breakpoint at errfinish, which works
independently of just where the call is.
