`:source` command does not skip `if 0`

[wsd...@outlook.com]

Hello, I just found a issue with vim.7.4.1689, and this also happened in 8.0.0027.

Down load vim from https://github.com/vim/vim-win32-installer/releases/download/v8.0.0027/gvim_8.0.0027_x64.zip.

the vimrc file is:

```

filetype off
set rtp+=build/vader
set rtp+=.
set rtp+=after
set noswapfile
filetype plugin indent on
syntax enable
set nocompatible

```

and the test.vim is:

```

  if 0
     lua spacevim_dict = 1
  else
    echo 'skip lua test'
  endif

```

run command: `vim -Nu vimrc test.vim` and `:so %`. I get error like:

```

处理 C:\Users\wsdjeg\Desktop\test.vim 时发生错误:

第    3 行:

E370: 无法加载库 lua53.dll

Lua library cannot be loaded.

```

I cannot reproduce with latest version. gvim 8.0.0027 is from 2016, I
guess it has been fixed in the meantime.

Thanks,
Christian

Yeah, I also can not reproduce it in latest version, but for some reason I need to use vim74 or vim8 in old windows PC. is there any workaround ti skip this error?

Try to wrap it into an exe call:
```
if 0
exe ":lua spacevi_dict=1"
endif
```

Or add an explicit finish before the lua line:
```
if !has('lua') " or whatever condition
finish
endif
lua spacevi_dict=1
```

Thanks,
Christian
