That was my bad. Your expression seems to have worked. Thanks!

Would you mind expaining a bit about why it works? Per my current
understanding, both mine and yours should have the same net effect,
except that marking the inner group non-capturing should make the regex
evaluation a bit faster because emacs need not remember the matched
text. But clearly, my understanding isn't correct.
