Ah, yes i actually tried hard to get rid of that habit, since i've
been writing pure(ish) C. Never the less i do like the idea of eg.
shock-horror,  for (int i=0;...) 
I'm not sure where else C++ would differ from C as far as auto vars are 
concerned, but it's probably not important.

I'd like to have a look at this, at first read it seemed simple, but the 
more i think about it the more complicated it gets.
I'm not sure if i get this slididng business.It sounds like just a few ifs
and memmoves,perhaps the buffer would need to be padded with spaces too. 
Although i have a feeling that my editgets.cpp function would be doing 
something similar, in insert mode(it works on a malloced length char*).
