Re: Odd behaviour with :q!

Doh! I moved /etc/virc (which is surely an aberrant rc filename for vim) on the wrong server (I have 4 hops to get to the one in question).  It is that.
Here's the file if you're interested (I'm going to remove it):

grahamn@gn-linux:~/remotes$ clear ; cat virc
if v:lang =~ "utf8$" || v:lang =~ "UTF-8$"
   set fileencodings=ucs-bom,utf-8,latin1
endif

set nocompatible        " Use Vim defaults (much better!)
set bs=indent,eol,start         " allow backspacing over everything in insert mode
"set ai                 " always set autoindenting on
"set backup             " keep a backup file
set viminfo='20,\"50    " read/write a .viminfo file, don't store more
                        " than 50 lines of registers
set history=50          " keep 50 lines of command line history
set ruler               " show the cursor position all the time

" Only do this part when compiled with support for autocommands
if has("autocmd")
  augroup redhat
  autocmd!
  " In text files, always limit the width of text to 78 characters
  autocmd BufRead *.txt set tw=78
  " When editing a file, always jump to the last cursor position
  autocmd BufReadPost *
  \ if line("'\"") > 0 && line ("'\"") <= line("$") |
  \   exe "normal! g'\"" |
  \ endif
  " don't write swapfile on most commonly used directories for NFS mounts or USB sticks
  autocmd BufNewFile,BufReadPre /media/*,/mnt/* set directory=~/tmp,/var/tmp,/tmp
  " start with spec file template
  autocmd BufNewFile *.spec 0r /usr/share/vim/vimfiles/template.spec
  augroup END
endif

if has("cscope") && filereadable("/usr/bin/cscope")
   set csprg=/usr/bin/cscope
   set csto=0
   set cst
   set nocsverb
   " add any database in current directory
   if filereadable("cscope.out")
      cs add cscope.out
   " else add database pointed to by environment
   elseif $CSCOPE_DB != ""
      cs add $CSCOPE_DB
   endif
   set csverb
endif

" Switch syntax highlighting on, when the terminal has colors
" Also switch on highlighting the last used search pattern.
if &t_Co > 2 || has("gui_running")
  syntax on
  set hlsearch
endif

filetype plugin on

if &term=="xterm"
     set t_Co=8
     set t_Sb=dm
     set t_Sf=dm
endif

" Don't wake up system with blinking cursor:
let &guicursor = &guicursor . ",a:blinkon0"

It would be more helpful to know what plugins and non-standard
settings you have.  I'm going to guess that if you repeatedly try

  vim -u NONE ...

it shouldn't give you any trouble.  If it does, then there's
something much shadier going on.  If that works just fine, there's
likely some mapping interfering with your command.

I also presume that, if you type ":q!" in other programs, such as
another text-editor or the command-shell, you have no problems
(ruling out a flaky keyboard like the built-in one on my laptop here
where the ZAQ1!<tab> cluster is broken).
