When creating a new (freestyle) job by copying some existing job:

1) If the existing job name begins with whitespace, the dropdown list does not work.

2) If the existing job name begins or ends with whitespace, after submitting the form we get "Error: No such job: name"

It's not obvious in either case that extra whitespace is the problem.

Typically the whitespace comes from copying/pasting a job name from the list in the view UI, so this bug just makes that a bit less convenient.
