Line by line is a good choice. But if you don't want to block the UI (by 
running the "save as" in an idle loop, chunk by chunk, for example), the 
document can be modified during the save. It's simpler to save 
synchronously, so the document can not be modified.

If you want to take into account the encoding, the line ending type and 
some other flags, you will end up with the gedit document saver:
https://git.gnome.org/browse/gedit/tree/gedit/gedit-document-saver.h

A plan is to make the document loader and saver reusable. For example by 
moving the code in GtkSourceView. The API must be a little modified 
(e.g. to support your use case).

You can save the location before the "save as", and then restore the 
location, but I agree it's not fantastic.

Hope this helps,
