实在是不喜欢将这种针对某种类型的插件放在plugin目录，因为这样不论打开什么类型的文件都会加载插件。之前c-support就被我扔到ftplugin了，一点问题没有。但perl-support有点小问题（虽然两个插件出自一个作者之手），原因是perl-support中的autocmd用的是BufNewFile,BufRead触发事件，改成FileType就行了。
另外还要将perl-support.vim和ftplugin中的perl.vim合并成perl.vim放于ftplugin下，不能分开放在ftplugin/perl/目录下，某则linux下会找不到template文件
修改perl-support.vim最后几行如下：
