On IRC Chris AtLee reported, that vcs_info's mercurial backend fails
to detect very very old mercurial repositories. Seth House dug back into
history and found out that checking for .hg/data will work these ancient
repositories.
This changes VCS_INFO_bydir_detect() to be able to check for more than
one file in `${vcs_comm[detect_need_file]}'. This limits file names
in that variable to not include spaces. That is not an issue currently
and shouldn't be in the future.
In essence, this looks for .hg/store to detect current repositories and
for .hg/data for ancient ones.
