"Revision to strip" input field should strip whitespace (BB-9421)
Small detail: when I enter a revision to strip on the
/<user>/<repo>/admin/strip page, whitespace isn't removed from the value before you try to look it up.
Since the value I enter often comes from some text I've selected with the mouse, I'll often include a space before or after the value. It would be nice if you stripped that before reporting that the revision cannot be found.
