[issue565] export -o<file> only handles last changeset

[bigblackdog]

New submission from bigblackdog <bigblackdog-mercurial at uwe-husmann.de>:

to reproduce the error follow these steps:
$ hg clone http://www.selenic.com/repo/hello my-hello
$ cd my-hello
$ vim hello.c
make some change
$ hg commit -m"modified hello.c"
$ vim Makefile
make some change
$ hg commit -m"modified Makefile"
$ hg export -o changes.diff 2:tip

now, changes.diff only contains changes made in the last changeset.
