"Firstly, I'd like to thank everybody who mailed me about my last vi tutorial for their kind words - and for asking for more!
I also want to clarify that I am not using vi itself but the better known clone called 'vim' which has been ported to a number of
different operating systems (Linux, Beos, VMS, DOS, Windows and Amiga to name but a few) and is available for download at
the vim website, www.vim.org. I'm mentioning this because there is a chance that I might accidentally describe some vim
specific functionality and would greatly appreciate it if corrections were emailed to me. Anyways, time to get on with it..."
"Lines.
There is one mildly annoying thing about vi, which is that for the most part you don't know for certain if one line of text is
displayed as just one line or whether it might be so long as to wrap around and be displayed on the screen as being two or more
lines. This can be extremely annoying if for example you delete four lines and, due to word wrap, you really only should have
deleted two."
