trim leading and trailing whitespace from search

[neilb]

I just tried searching for "JOROL " (without the double quotes, where are here to show the trailing space), and didn't get his account listed at the top. I had pasted his PAUSE id from an email and accidentally picked up the trailing space.

Deleting the space and searching again resulted in the expected user account.

Seems easy, maybe something I could take on?
