largefiles: make prompt order deterministic

42ae1b1f048f introduced iteration of a set. Make it stable.

  $ hg init a
  $ cd a
  $ echo 'root' >root
  $ hg add root
  $ hg commit -d '0 0' -m "Adding root node"

  $ echo 'a' >a
  $ hg add a
  $ hg branch a
  marked working directory as branch a
  (branches are permanent and global, did you want a bookmark?)
  $ hg commit -d '1 0' -m "Adding a branch"

  $ hg branch q
  marked working directory as branch q
  $ echo 'aa' >a
  $ hg branch -C
  reset working directory to branch a
  $ hg commit -d '2 0' -m "Adding to a branch"

  $ hg update -C 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo 'b' >b
  $ hg add b
  $ hg branch b
  marked working directory as branch b
  $ hg commit -d '2 0' -m "Adding b branch"

  $ echo 'bh1' >bh1
  $ hg add bh1
  $ hg commit -d '3 0' -m "Adding b branch head 1"

  $ hg update -C 2
  1 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ echo 'bh2' >bh2
  $ hg add bh2
  $ hg commit -d '4 0' -m "Adding b branch head 2"

  $ echo 'c' >c
  $ hg add c
  $ hg branch c
  marked working directory as branch c
  $ hg commit -d '5 0' -m "Adding c branch"

reserved names

  $ hg branch tip
  abort: the name 'tip' is reserved
  [255]
  $ hg branch null
  abort: the name 'null' is reserved
  [255]
  $ hg branch .
  abort: the name '.' is reserved
  [255]

invalid characters

  $ hg branch 'foo:bar'
  abort: ':' cannot be used in a name
  [255]

  $ hg branch 'foo
  > bar'
  abort: '\n' cannot be used in a name
  [255]

trailing or leading spaces should be stripped before testing duplicates

  $ hg branch 'b '
  abort: a branch of the same name already exists
  (use 'hg update' to switch to it)
  [255]

  $ hg branch ' b'
  abort: a branch of the same name already exists
  (use 'hg update' to switch to it)
  [255]

verify update will accept invalid legacy branch names

Tests of revision branch name caching

We rev branch cache is updated automatically. In these tests we use a trick to
trigger rebuilds. We remove the branch head cache and run 'hg head' to cause a
rebuild that also will populate the rev branch cache.

revision branch cache is created when building the branch head cache
  $ rm -rf .hg/cache; hg head a -T '{rev}\n'

cache is updated/truncated when stripping - it is thus very hard to get in a
situation where the cache is out of sync and the hash check detects it
  $ hg --config extensions.strip= strip -r tip --nob
