test-pushvars: invoke shell script hook via `sh` for Windows

Invoking *.sh on Windows leads to the "what program should open this?" prompt,
which stalls the test and led to the recent series of exceptions on the Windows
test machine as the runner times out.

Make sure update doesn't assume b1 is a repository if invoked from outside:

  $ cd ..
  $ hg update b1
  abort: no repository found in '$TESTTMP' (.hg not found)!

  $ cd b1

Test updating with closed head
---------------------------------------------------------------------

  $ hg clone -U -q b1 closed-heads
  $ cd closed-heads

Test updating if at least one non-closed branch head exists

if on the closed branch head:
- update to "."
- "updated to a closed branch head ...." message is displayed
- "N other heads for ...." message is displayed

  $ hg update -q -C 3
  $ hg commit --close-branch -m 6
  $ norevtest "on closed branch head" clean 6
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  no open descendant heads on branch "default", updating to a closed head
  (committing will reopen the head, use 'hg heads .' to see 1 other heads)
  parent=6

if descendant non-closed branch head exists, and it is only one branch head:
- update to it, even if its revision is less than closed one
- "N other heads for ...." message isn't displayed

  $ norevtest "non-closed 2 should be chosen" clean 1
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  parent=2

if all descendant branch heads are closed, but there is another branch head:
- update to the tipmost descendant head
- "updated to a closed branch head ...." message is displayed
- "N other heads for ...." message is displayed

  $ norevtest "all descendant branch heads are closed" clean 3
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  no open descendant heads on branch "default", updating to a closed head
  (committing will reopen the head, use 'hg heads .' to see 1 other heads)

Test updating if all branch heads are closed

if on the closed branch head:

if not on the closed branch head:
- update to the tipmost descendant (closed) head
- "updated to a closed branch head ...." message is displayed

  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

Test updating if "default" branch doesn't exist and no revision is
checked out (= "default" is used as current branch)

  $ hg init no-default-branch
  $ cd no-default-branch

  $ hg branch foobar
  marked working directory as branch foobar
  (branches are permanent and global, did you want a bookmark?)
  $ echo a > a
  $ hg commit -m "#0" -A
  adding a
  $ echo 1 >> a
  $ hg commit -m "#1"
  $ hg update -q 0
  $ echo 3 >> a
  $ hg commit -m "#2"
  created new head
  $ hg commit --close-branch -m "#3"

if there is at least one non-closed branch head:
- update to the tipmost branch head

  $ norevtest "non-closed 1 should be chosen" clean null
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  parent=1

if all branch heads are closed
- update to "tip"
- "updated to a closed branch head ...." message is displayed
- "all heads for branch "XXXX" are closed" message is displayed

  $ hg update -q -C 1
  $ hg commit --close-branch -m "#4"

  $ norevtest "all branches are closed" clean null

Test obsolescence behavior

successors should be taken in account when checking head destination

  $ cat << EOF >> $HGRCPATH

Test that we don't crash when updating from a pruned changeset (i.e. has no
successors). Behavior should probably be that we update to the first
non-obsolete parent but that will be decided later.
