如果GTAGS文件是空的话，会在编辑区弹出报错：
gtags: .LfCache/gtags/____/GTAGS seems corrupted.

参考：ludovicchabant/vim-gutentags#225

Steps to reproduce

Actual behaviour

Expected behaviour

[Yggdroot]

重新生成。

[guoang]

重新生成也还是会报错，因为这个仓库就是没有tags的，但是我又想保留 let g:Lf_GtagsAutoGenerate = 1，所以最好是对空的GTAGS不要报错就好了。
另外对于比较大的仓库，后台生成tags期间，GTAGS文件也是空的，这个时候就也会报错。

[Yggdroot]

这个错误怎么复现？

[ouyangjunyi]

这个错误怎么复现？

大佬，我这边也遇到只要项目大一点，生成的tags就是空的，这个怎么过滤只对特定后缀的文件进行索引呢？

Lines 657 to 678 in f55c96b

	g:Lf_GtagsSource *g:Lf_GtagsSource*
	Gtags accepts a list of files as target files. This option indicates
	where the target files come from. It has 3 values: 0, 1, 2.
	0 - gtags search the target files by itself.
	1 - the target files come from FileExplorer.
	2 - the target files come from |g:Lf_GtagsfilesCmd|.
	Default value is 0.
	g:Lf_GtagsfilesCmd *g:Lf_GtagsfilesCmd*
	If |g:Lf_GtagsSource| is 2, use the command defined by this option to
	generate the target files.
	Default value is: >
	let g:Lf_GtagsfilesCmd = {
	\ '.git': 'git ls-files --recurse-submodules',
	\ '.hg': 'hg files',
	\ 'default': 'rg --no-messages --files'
	\}
	<
	, which means use command `git ls-files --recurse-submodules` for git
	repository and `hg files` for hg repository, use `rg --no-messages --files`
	otherwise.

这个问题复现方法：
下一个 AOSP 全套代码执行
Leaderf gtags --update --debug
cd "/home2/zmcai/sm8350_i5" && gtags -i --skip-symlink --gtagslabel default “/home/zmcai/.LfCache/gtags/_home2_zmcai_sm8350_i5
如果没有设定:GTAGSFORCECPP=1:，就会发生 gtags 产生 GTAGS 错误。之后如果不删除一直产生 corrupted 错误。
