`preview.sh` is inaccessible under Windows by default.

• I have fzf 0.30.0 or above
• I have read through https://github.com/junegunn/fzf.vim/blob/master/README.md
• I have read through https://github.com/junegunn/fzf/blob/master/README-VIM.md
• I have read through the manual page of fzf (man fzf)
• I have searched through the existing issues

Under Windows, I'm unable to get a preview by running the default :Files command.

Following further investigation, I found out that it is possible to run the preview.sh file but with the following modification.

bash /mnt/c/Users/milen/.cache/dein/repos/github.com/junegunn/fzf.vim/bin/preview.sh

In fact, anything will work when the /mnt/c/ section is provided even with a simpler path. So the following also works.

bash /mnt/c/Users/milen/preview.sh

So the command(s) above are working, however the defaults are unable to execute preview.sh. What would be the simplest way to pass that information to fzf.vim.

So this is working:

command! -bang -nargs=? -complete=dir MyFiles
    \ call fzf#vim#files(<q-args>, {'options': ['--layout=reverse', '--info=inline', '--preview', 'bash /mnt/c/Users/milen/preview.sh {}']}, <bang>0)

But it is not working when in drive W:\.

When using the preview.sh, I'm getting the following error:
<3>WSL (34590) ERROR: CreateProcessParseCommon:711: Failed to translate W:\

I can confirm the following is working on drive W:\.
command! -bang -nargs=? -complete=dir Files call fzf#run(fzf#wrap({'options': ['--preview', 'bat {}']}))

Can you update fzf and fzf.vim to the latest and see if it helps?
