Yes but I'm not writing binary (or even C) code here. I'm using a = high-level language that is supposed to hide the complexity of all that = machinery and help me think at a higher level. > As Stefan noted the Emacs workflow is not all that > different from what you could do with most popular APIs (POSIX, WIN32, > etc).

I was na=C3=AFvely thinking that inserting contents in a file is a = frequent enough task (think xml nodes for ex), and actually even more = frequent than appending, that there would be a relatively standard = workflow proposed in the reference. Stephan proposed that we consider inserting some extra info in the = reference. When I'm done sorting my thing, I'll work on that.
