    Don't break when data-dir is null. · d0c3defe
    quasicomputational authored and Oleg Grenrus's avatar Oleg Grenrus committed
    PR #5284 changed things around, and now matchDirFileGlob will break if
    it's passed a null directory, which happens to be the default value
    for data-dir. Its call sites have been fixed to check for this and to
    substitute '.' for an empty path, which is the desired behaviour; in
    addition, matchDirFileGlob itself will now warn about this if it's
    detected, so that new broken call sites can't sneak in.
    Fixes #5318.
