Globbing is usually used for filenames, so on windows it is reasonable and very
convenient that glob patterns accepts '\' or '/' when the pattern specifies
'/'.
Previously, pull would not update if new branch heads were received,
whereas pull && update would move to the tipmost branch head.
Also change the "crosses branches" abort in merge.update from
"crosses branches (merge branches or use --check to force update)"
to
"crosses branches (merge branches or update --check to force update)"
since it can no longer assume the user is running hg update.
A bookmark can only move to a descendant on commit, pull or
unbundle. Bookmarks cannot jump between heads anymore. This fixese
issue 1502.
We explicitly use new.node(), to emphasise that we are updating the
current bookmark to the new node.
