templatekw: make {successorssets} always return a list (issue6342)

Previously, {successorssets} returns an empty string instead of an empty list

hard to consume from statically-typed languages.

Differential Revision: https://phab.mercurial-scm.org/D9158

This test file test the various templates related to obsmarkers.

Test metadata encoding (issue5754)
==================================

  $ hg init $TESTTMP/metadata-encoding

  $ cat <<'EOF' >> .hg/hgrc

  $ mkcommit ROOT
  $ ( HGENCODING=latin-1 HGUSER="`cat test1`" mkcommit A0 )
  $ echo 42 >> A0
  $ HGENCODING=latin-1 hg amend -m "A1" --note "`cat test2`"
  $ HGENCODING=latin-1 hg amend -m "A2" \

  $ mkcommit B0
  $ HGENCODING=latin-1 hg debugobsolete -u "`cat test2`" "`getid 'desc(B0)'`"
  1 new obsolescence markers
  obsoleted 1 changesets

metadata should be stored in UTF-8, and debugobsolete doesn't decode it to
local encoding since the command is supposed to show unmodified content:

  $ HGENCODING=latin-1 hg debugobsolete

metadata should be converted back to local encoding when displaying:
