Hi Tony,
I was actually writing a plugin for this, and since I could change its
implementation I ended up with something like (note the call to
substitute() right after system()):
function! s:paste(...) " {{{
let l:after = get(a:, 1, 1)
let reg_save = @@
let @@ = system(g:cb_paste_prg)
" XXX pastin on Windows somehow leaves trailing ^M
" gotta figure out a better way to fix this, but
" for now, this will do!
let @@ = substitute(@@, "\r\n", "\n", "g")
setlocal paste
if l:after
exe 'normal p'
else
exe 'normal P'
endif
setlocal nopaste
let @@ = reg_save
endfunction " }}}
I will leave this here for a little while, and then I will probably
cross-post it on vim_dev.
Thanks again for the help.
