prev: prompt user to choose parent in case of multiple parents

This patch adds functionality to `hg prev` to prompt user to choose one parent
to update when multiple parents exist.

Surprisingly there were no tests for this case before this patch, I added one
with this patch.

import hghave

@hghave.check("docgraph-ext", "Extension to generate graph from repository")
def docgraph():
    try:
        import hgext.docgraph
        hgext.docgraph.cmdtable # trigger import
    except ImportError:
        try:
            import hgext3rd.docgraph
            hgext3rd.docgraph.cmdtable # trigger import
        except ImportError:
            return False
    return True
