hg.bat: return exit code explicitly for indirect invocation
When "hg.bat" is invoked via interactive shell "cmd.exe" on Windows,
it can store own exit code into ERRORLEVEL correctly, regardless of
explicit "exit" statement in it: "cmd.exe" seems to hold ERRORLEVEL
updated by the last command in the batch file (= "python hg", in
"hg.bat" case).
On the other hand, "hg.bat" is invoked indirectly via
"subprocess.Popen" (e.g. shell alias, hooks, hgclient and so on), the
parent process always receives exit code 0 from spawned "hg.bat":
batch files on Windows seem not to be really spawned like as shell
scripts on UNIX, but to be executed in the "cmd.exe" process.
This patch returns exit code explicitly for indirect invocation.
"/b" should be specified for "exit" to prevent "cmd.exe" from being
terminated when "hg.bat" is invoked interactively from it.

test deleting .hg/bookmarks.current when explicitly updating
to a revision
$ echo a >> b
$ hg ci -m.
$ hg up -q X
$ test -f .hg/bookmarks.current
try to update to it again to make sure we don't
set and then unset it
$ hg up -q X
$ test -f .hg/bookmarks.current
$ hg up -q 1
$ test -f .hg/bookmarks.current

when a bookmark is active, hg up -r . is
analogous to hg book -i <active bookmark>
$ hg up -q X
$ hg up -q .
$ test -f .hg/bookmarks.current
