PATCH: (2/2) Make the hg backend work with new versions of mercurial



VCS_INFO_bydir_detect() now accepts every kind of file in
${vcs_comm[detect_need_file]} not just plain files.

The hg backend uses that by detecting via (paraphrased):
[[ -d .hg ]] && [[ -e .hg/store ]]
where .hg/store is a directory.

If .hg/branch is missing, the branch name defaults to 'default'.
