PrevieTag not working with Gtags

[wlmei]

When using ":PreviewTag funcNamexxx" in VIM, it will complain:
E257: preview: tag not find funcNamexxx

These tags were generated using 'gtags'

I have the same issue. Do you have fix it?

这个不是错误，是 vim 的内建 taglist() 函数只支持 ctags，你用 gutentags 自动生成 ctags 数据库就行了嘛。
