It's almost certainly a typo, but it introduces no bug because '*' can't bear its special meaning after '^', so the regexp engine will make it match exactly the '*' character. But it'd be better written as "^*+" (but this is not recommended) or, preferably, "^\\*+" indeed. Here's the relevant manual excerpt from (info "(elisp) Regexp Special") : > *Please note:* For historical compatibility, special characters are > treated as ordinary ones if they are in contexts where their special > meanings make no sense.
