some rpm build improvements

Version XX

Daniel (8 April 2000):

- Made the progress bar look better for file sizes between 9999 kilobytes

  and 100 megabytes. They're now displayed XX.XM.

- I also noticed that ftp fetches through HTTP proxies didn't add the user

  agent string. It does now.

- Habibie <habibie@MailandNews.com> supplied a pretty good way to build RPMs

  on a Linux machine. It still a) requires me to be root to do it, b) leaves

  the rpm packages laying at some odd place on my disk c) doesn't work to

  build the ssl version of curl since I didn't install openssl from an rpm

  package so now the rpm crap thinks I don't have openssl and refuses to build

  a package that depends on ssl... Did I mention I don't get along with RPM?

- Marco G. Salvagno <mgs@whiz.cjb.net> supplied me with two fixes that

  appearantly makes the OS/2 port work better with multiple URLs.
