This appears to be introduced in the commit [1]. I couldn't find any
explanation of the change of regexp in the previous commit to this commit.

More specifically, in the previous commit, the regexp had [:>|}] character
alternative. But this commit changes it to []>|}+]. Why is ] included in
this character alternative?
