optparse style indentation with continuation wrong

[lnussbaum]

Test case:

opts.on('--coordinator host=HOST[,port=PORT]',
        'Specify the HOST and the PORT of the coordinator') do |str|
          h = sub_opts_to_hash(str)
        end

I expect "end" to be aligned with "opts.on"

Thanks for the report. Just pushed a fix to master.
