phase: alway return a value

With the previous code, the phase command was returning None when displaying
phase and 0 or 1 when moving them.

This seemed an bit odd and displaying phase return 0 too now.

run only on case-insensitive filesystems

  $ "$TESTDIR/hghave" icasefs || exit 80

  $ hg init repo1
  $ cd repo1

create base revision

  $ echo base > base.txt
  $ hg add base.txt
  $ hg commit -m 'base'

add same file in different case on both heads

  $ echo a > a.txt
  $ hg add a.txt
  $ hg commit -m 'add a.txt'

  $ hg update 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

  $ echo A > A.TXT
  $ hg add A.TXT
  $ hg commit -m 'add A.TXT'
  created new head

merge another, and fail with case-folding collision

  $ hg merge
  abort: case-folding collision between a.txt and A.TXT

update to base revision, and modify 'a'

  $ hg update 0
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo 'this is added line' >> a

update to current tip linearly

  $ hg update 1
  merging a and A to A
  0 files updated, 1 files merged, 0 files removed, 0 files unresolved

check status and contents of file

  $ hg status -A
