Two questions regarding page numbers

[胡海鹏 - Hu Haipeng]

Hello,
  I have two questions about title pages and prefaced pages. Perhaps they are in the manuals, but I can't find them at this time.
  1. Title pages: If I want to set page number to -1 to start the music at the second piece of paper, how can I force the number 0 to hide at the back of title page? I tried

\paper {
  print-page-number = ##f
}

at first, then after the small intro text on the back, added another paper block to turn on page numbering before the music. But this results the same as if no previous setting was used. How can I do?

  2. How can I make the preface Roman page numbered? And then how can I reset the beginning of music page 1 (Arabic)?

Regards
Haipeng

PS. I'm totally frustrated with the latest versions of devel, whose spacing is becoming stranger and stranger. My overture got 34 pages on 2.13.24, and then 38 on 2.13.31, and at last 50 on 2.13.33! Also, my drums can't go into midi now, even rolling back to 2.13.24. I'll try more to solve it.
