[tex-k] Unsupported extra colon in kpsewhich --expand-path

[Karl Berry]

      TEXMFSCRIPTS=.: kpsewhich --expand-path '$TEXMFSCRIPTS'
    find only ".", the setting in texmf.cnf is ignored,

Indeed, seems like a bug.  I'll look into it as soon as I can (unless
you or Akira or anyone else wants to delve :).
