ooo -- Rex -- i didn't know about that one

here's an alternative i came up with -- it always seemed
natural to me when opening netrw to do so with the cursor at
the current buffer -- for this i came up with the following
function:

function! MyExplore(s)
if a:s == "t"
call MyExploret()
return
endif
let save_locate = @/
let @/ = '\<' . escape(expand("%:t"), ' .\')
let g:netrw_sort_by = "name"
let g:netrw_sort_direction = "normal"
if &modified
Sexplore .
else
Explore .
endif
normal gg
try
silent normal n
normal zz
catch
endtry
let @/ = save_locate
endfunction

nmap <silent> <S-F11> :call MyExplore('')<CR>
imap <silent> <S-F11> <ESC>:call MyExplore('')<CR>

i probably don't need the test for &modified any more since
setting 'confirm' in my .vimrc, but it looks good in there, so
i'm leaving it
