(bug 40646) Errant line break in "Use a different license option"

Steps to see where the line break was:
1. Upload multiple files on uploadwizard
2. Select "Provide copyright information for each file individually on the next page"
3. Select "this is my own file work" and then "use a different license option"

In the <label> used to display various options with radio buttons, text-indent is set as 0px to match the indentation, gave padding-top:2px to separate between the two labels
But then the radio buttons were not displayed at proper places so used vertical-align:top in input['type'=radio].mwe-upwiz-copyright-info, the class is added in mw.UploadWizardLicenseInput.js as $input.addClass('mwe-upwiz-copyright-info-radio').
Since the break was occuring at "legal" which did not suit, so used <br> before the parenthesis in i18n
