reachableroots: fix transposition of set and list types in PyArg_ParseTuple

This is being masked by the function not properly returning NULL when
it raises an exception, so the client code was just falling back to
the native codepath when it got None back. A future change removes all
reason for this C function to return None, which exposed this problem
during development.

  $ hg init source
  $ cd source
  $ echo a > a
  $ hg ci -qAm adda

Add a merge with one parent in the same branch

  $ echo a >> a
  $ hg ci -qAm changea
  $ hg up -qC 0
  $ hg branch branch0
  marked working directory as branch branch0
  (branches are permanent and global, did you want a bookmark?)
  $ echo b > b
  $ hg ci -qAm addb
  $ hg up -qC
  $ hg merge default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg ci -qm mergeab
  $ hg tag -ql mergeab
  $ cd ..

Miss perl... sometimes

  $ cat > filter.py <<EOF
  > import sys, re
  > 
  > r = re.compile(r'^(?:\d+|pulling from)')
  > sys.stdout.writelines([l for l in sys.stdin if r.search(l)])
  > EOF

Add a merge with both parents and child in different branches

  $ cd source
  $ hg branch branch1
  marked working directory as branch branch1
  $ echo a > file1
  $ hg ci -qAm c1
  $ hg up -qC mergeab
  $ hg branch branch2
  marked working directory as branch branch2
  $ echo a > file2
  $ hg ci -qAm c2
  $ hg merge branch1
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg branch branch3
  marked working directory as branch branch3
  $ hg ci -qAm c3
  $ cd ..
