A small patch to fix building darcs with cabal new-build (1.24).
New stanza should be ignored without errors using Cabal >= 1.20

I am using new-build since quite a while and had no problems. It is
unclear to me what the purpose is of the extra stanza .

From what I recall, it's reproducible with cabal-install 1.24 but not 
cabal-install 2.0 (still in beta).

Ah, that may be it. I am using the cabal-head package for ubuntu.

I have pushed the patch to screened.

fa-ml writes (personal communication):

"""
I have talked with cabal devs (in the person or Herbert Valerio
Riedel).

Long story short: the stanza will become mandatory once cabal-version
hits 1.24.

I asked why using HEAD required no change, answer was: "It is probably
just accidental/coincidental".

So I believe the problem stands, and users who are currently using
some cabal versions (1.24+ and soon, HEAD) will get bitten by this.
"""

I guess that means we have to bite the bullet and accept this patch even
though it burdens us with duplicate dependency information in the cabal
file?

I checked and found that my cabal-head is now at version 2.1 which
explains why it works for me w/o the extra stanza.
