解决方法
从
Emacs manual “Visiting Files” section:
If the file name you specify contains shell-style wildcard characters,
Emacs visits all the files that match it. (On case-insensitive
filesystems,Emacs matches the wildcards disregarding the letter
case.) Wildcards include ‘?’,‘*’,and ‘[…]’ sequences.
所以这些不是正则表达式;它们很简单shell-style wildcards.匹配任何单个字符,*匹配零个或多个字符,[abc]匹配任何字符a,b或c.
