test-merge5: ensure updating to tip across branches is tested

When doing "hg update" across branches (without any revision
specified), hg will abort and ask the user to merge or do hg update
-c. This tests for that error.

  $ mkdir t
  $ cd t
  $ hg init
  $ echo This is file a1 > a
  $ echo This is file b1 > b
  $ hg add a b
  $ hg commit -m "commit #0" -d "1000000 0"
  $ echo This is file b22 > b
  $ hg commit -m"comment #1" -d "1000000 0"
  $ hg update 0
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ rm b
  $ hg commit -A -m"comment #2" -d "1000000 0"
  removing b
  created new head
  $ hg update 1
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg update
  abort: crosses branches (use 'hg merge' or use 'hg update -c')
  $ hg update -c
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ mv a c
in theory, we shouldn't need the "-y" below, but it prevents
this test from hanging when "hg update" erroneously prompts the
user for "keep or delete"

should abort
  $ hg update -y 1
  abort: crosses branches (use 'hg merge' to merge or use 'hg update -C' to discard changes)
  $ mv c a
should succeed
  $ hg update -y 1
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ exit 0
