Pan 0.11.2.91 Beta released

This version fixes a pair of yEnc bugs. It also adds a button to jump back to the previous read article, recognition of non-standard quote prefix characters, support for articles that specify x-uuencode encoding in mime headers, and small usability improvements. March 28, 2002 - New Release:
0.11.2.91 "In Your Valley, Beneath Your Sky"

New Features
• Added the ability to specify which characters are recognized
  as quote prefix characters, so nonconformists not using '>' to
  quote text will still have their articles colored right in Pan. :)
  Thanks to Colin Leroy for contributing this code.

  Jeff Stedfast for this code.

• Fixed a bug in Follow-Up that caused some new text typed in by
  the user to be colored in the quoted-text color rather than the
  normal text color. Thanks to Michael McIntyre for reporting this bug.

• If a yenc block ends without a "=yend", or a uu block ends
  without an "end", treat the block as plaintext instead of encoded
  data. Looks like some M$ bashers are starting their posts with
  "begin 666" to tickle a similar bug in OE. :)
  Thanks to Jason Rumney and mr_p for reporting this bug.

• Make sure that the default window size is large enough that a
  full line, up to the default number of wrap characters and with
  the default font, will fit without scrolling. Thanks to John Mellor
  for suggesting this obvious-in-hindsight improvement. :)
