I have exactly the same problem with '_' and '__' in words, so I would like the
feature also, if it is possible.
That said, you can use something like the following to get by in the meantime:
function! SelectCustomWord()
let l:oldISK = &isk
let l:oldSearch = @/
set isk+=\-
normal! v?\<\|--?e+1
mto`t/\>\|--/s-1
let &isk = l:oldISK
let @/ = l:oldSearch
nohls
endfunction
" enable using 'yi-' just like you use 'yiw'
onoremap i- :call SelectCustomWord()<CR>
vnoremap i- v:call SelectCustomWord()<CR>
" a mapping for you to try stuff out
map <F5> "ayi-:echo @a<CR>
Then you can use 'i-' just like you would use 'iw'. here's some words for you
to try it on (press F5 with the cursor over different words):
"one-word"
two--words
first-word--second-word--thirdword!
See ':help text-objects' and ':help iw' for more information on how to use 'iw'
and your new 'i-' command.

Peter
