  Have script_helper._assert_python strip refcount strings from stderr.

  This makes the output of the function and those that depend on it
  independent of whether or not they are being run under a debug
  build.

  Fix formatting of values with embedded newlines when rfc2047 encoding

  Before this patch if a value being encoded had an embedded newline,
  the line following the newline would have no leading whitespace,
  and the whitespace it did have was encoded into the word.  Now
  the existing whitespace gets turned into a blank, the way it does
  in other header reformatting, and the _continuation_ws gets added
  at the beginning of the encoded line.

  #10960: fix 'stat' links, link to lstat from stat, general tidy of stat doc.

  Original patch by Michal Nowikowski, with some additions and wording
  fixes by me.

  I changed the wording from 'Performs a stat system call' to 'Performs
  the equivalent of a stat system call', since on Windows there are no
  stat/lstat system calls involved.  I also extended Michal's breakout
  of the attributes into a list to the other paragraphs, and rearranged
  the order of the paragraphs in the 'stat' docs to make it flow
  better and put it in what I think is a more logical/useful order.
