bundle: treat branches created newly on the local correctly (
issue3828)
Before this patch, "hg bundle --branch foo other" fails to create
bundle file, if specified "foo" branch is created newly on the local
repository.
"hg bundle" uses "hg.addbranchrevs(repo, other, ...)" to look branch
names up, even though other outgoing-like implementation uses
"hg.addbranchrevs(repo, repo, ...)". In the former invocation, "other"
repository recognizes such branches as unknown, so execution is
aborted.
This patch uses "hg.addbranchrevs(repo, repo, ..)" in "hg bundle" to
bundle revisions on such branches correctly.
