tests: accommodate both "hg-evolve" and "hg_evolve" in tarballs

Looks like current distutils (or maybe setuptools, I'm not an expert) that are
available in Debian Testing create tarballs that have an underscore instead of
a hyphen in the name.

The paths inside the tarball are also different, so we need to change the sed
instruction too.

Setting a topic namespace alone doesn't affect wdir()

  $ hg debug-topic-namespace space-name
  marked working directory as topic namespace: space-name
  $ hg debug-topic-namespaces
  space-name
  $ cat .hg/topic-namespace
  space-name (no-eol)

  $ hg log -r 'wdir()' -T '{topic_namespace}\n'
  none

  $ hg log -r 'wdir()' -T '{fqbn}\n'
  default

But after setting a topic the already-set namespace is visible on wdir()

  $ hg topic feature
  marked working directory as topic: feature
  $ hg topics
   * feature (0 changesets)

  $ hg log -r 'wdir()' -T '{topic_namespace}\n'
  space-name

  $ hg log -r 'wdir()' -T '{fqbn}\n'
  default//space-name/feature

Non-ascii topic namespace name

  $ hg debug-topic-namespace --clear
  $ test -f .hg/topic-namespace

  $ hg --encoding utf-8 debug-topic-namespace æ

  $ hg --encoding utf-8 debug-topic-namespace ©

  $ hg branch stable

Removing topic namespace file if it contains the default value

The default value changed from b'default' to b'none' in 11.1.0, this is a
safeguard against accidentally putting the new default tns value into commit
extras with an old version of topic extension

  $ printf 'none' > .hg/topic-namespace
  $ test -f .hg/topic-namespace
  $ hg ci -m ''
  nothing changed
  [1]
  $ test -f .hg/topic-namespace
  [1]

Updating to a revision with a namespace should activate it

  $ hg up null
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg debug-topic-namespace
  none
  $ test -f .hg/topic-namespace
  [1]
  $ hg topics
     feature (1 changesets)
  $ test -f .hg/topic
  [1]
  $ hg up 0
  switching to topic-namespace alice
  switching to topic feature
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg debug-topic-namespace
  alice
  $ cat .hg/topic-namespace
  alice (no-eol)
  $ hg topics
   * feature (1 changesets)
  $ cat .hg/topic
  feature (no-eol)

Updating to a topic namespace is not supported

  $ hg up alice
  abort: unknown revision 'alice'

Parsing

  $ hg debugparsefqbn foo/bar//user26/feature -T '[{branch}] <{topic_namespace}> ({topic})\n'
  [foo/bar] <user26> (feature)

no double slashes means it's a named branch
  $ hg debug-parse-fqbn foo/bar
  branch:    foo/bar
  namespace: none
  topic:     

Formatting

  $ hg debugformatfqbn -b branch -n namespace -t topic
  branch//namespace/topic

  $ hg debug-format-fqbn -n namespace
  //namespace/

  $ hg debug-format-fqbn -b foo/bar -n user26 -t feature
  foo/bar//user26/feature

default values

  $ hg debug-format-fqbn -b default -n none -t '' --no-short
