I'm not sure I understand what you are saying. My concern is that calls to
filebuf::seekoff(0,ios::cur) should not invalidate the buffer just to return a
correct answer to "where am I?". Whether this is an accident of history or not,
I've seen this usage enshrined in code as a respected idiom.

Does your text above specify this?
