That is a very substantial improvement and it now beats tobyink's non-regex solution, but cannot touch hdb's:

I'm not sure why you think it would be any easier to maintain that the non-regex solutions?

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority".

In the absence of evidence, opinion is indistinguishable from prejudice.
