Pass --extras parameter to c or cpp

[SunJun8]

Environment:

OS: x86_64 Linux 5.10.93.2-microsoft-standard-WSL2
Neovim version:NVIM v0.6.1
This plugin version: a0469c6
I'm using nvim-lsp:

plugin config

 nmap <silent> <F2> :Vista finder nvim_lsp<CR>
 let g:vista_default_executive = 'nvim_lsp'
 let g:vista_executive_for = {
   \ 'c': 'nvim_lsp',
   \ 'cpp': 'nvim_lsp',
   \ 'php': 'nvim_lsp',
   \ 'python': 'nvim_lsp',
   \ }
 let g:vista_fzf_preview = ['right:50%']
 let g:vista#renderer#enable_icon = 1

vista.vim/autoload/vista/executive/ctags.vim

Line 41 in a0469c6

let common_opt = '--format=2 --excmd=pattern --fields=+nksSaf --extras=+F --sort=no --append=no'

vista.vim/autoload/vista/executive/ctags.vim

Line 46 in a0469c6

let common_opt .= ' --extras= '

我对vim语法不是很了解，对我来说这里实际情况是目标文件为.c时，仍然传递了--extras=+F参数。删除--extras=+F即可正常工作，但这貌似并不是个通用方案
