bug#19576: write-file writes the wrong buffer

[Anders Lindgren]

Conceptually it should be easy to do that.  Save/restore current buffer,
selected window and frame.  But Alan (concerned about ‘follow-mode’),
Pip (who unfortunately disappeared) and Eli are currently discussing how
to fix ‘window-size-change-functions’ in various other ways as well.
I'll try to get the fix of this bug applied there too.

This sounds good!

If Alan has any thoughts on follow mode, I'd be happy to discuss them. I might need a bit of a refresher, though -- after all, I wrote it more than twenty years ago.
