== Vim options it turns out I want

[[This server http://gpu.utcc.utoronto.ca/]] recently moved from Fedora
Core 2 to FreeBSD, and in the process I discovered that I had quietly
become addicted to a few _vim_ features, despite [[past dislikes
HandsOffVi]] of overly intelligent things that call themselves _vi_.

(I am pleased to report that the default FreeBSD version of _vim_
does not behave [[that way HandsOffVi]].)

So it turns out to be necessary to set a few _vim_ parameters to get
it to behave the way I want. For my future reference, here's what I've
found I need to set in _$HOME/.vimrc_ so far:

- _set nocompatible_: This is the easiest way to get multi-level undo,
  which has become my single must have, cannot live without it _vim_
  feature.  (I should have expected this; I already knew that
  multi-level undo was addictive from using other editors with it.)

- _set backspace=indent,eol,start_: I have also gotten used to being able
  backspace over anything, end of line included.

- ((let loaded_matchparen = 1)): This is one of those anti-features; I do
  not want _vim_ to be freakily super-intelligent about (allegedly)
  matching delimiters.

I still sort of want _vim_ to behave like basic _vi_, but apparently
missing these features is now *too* basic for me. Such is the corrupting
experience of using Linux, with its array of convenient extensions and
GNU this and that.

(I care about this partly because I write most WanderingThoughts entries
on this machine in _vi_, mostly out of inertia and habit.)
