patchbomb: don't honor whitespace and format-changing diffopts (BC)

The whitespace diffopts break lossless transmission, and the format-changing
ones make import harder. We expect parsers to be able to read git-style diffs,
though.

Note for future hackers of patchbomb: this file is a bit heavy on
wildcards in test expectations due to how many things like hostnames
tend to make it into outputs. As a result, you may need to perform the
following regular expression substitutions:
@$HOSTNAME> -> @*> (glob)
Mercurial-patchbomb/.* -> Mercurial-patchbomb/* (glob)
/mixed; boundary="===+[0-9]+==" -> /mixed; boundary="===*== (glob)"
--===+[0-9]+=+--$ -> --===*=-- (glob)
--===+[0-9]+=+$ -> --===*= (glob)

  $ cat > prune-blank-after-boundary.py <<EOF
  > import sys
  > skipblank = False
  > trim = lambda x: x.strip(' \r\n')
  > for l in sys.stdin:
  >     if trim(l).endswith('=--') or trim(l).endswith('=='):
  >         skipblank = True
