{foo,bar} bad package location

[philderbeast]

If I use the {foo,bar} syntax for package locations then haskell-ci chokes. If I instead specify the same packages but listed individually haskell-ci is fine with that.

> ~/.cabal/bin/haskell-ci --output=.travis.yml --config=cabal.haskell-ci cabal.project
*ERROR* Bad package location: "../{foo,bar}/"

This syntax is described in the cabal docs.

Can we please say in the readme that the brace syntax is not supported?

Are we reusing the exact same globbing code that cabal-install uses, haskell/cabal#6732?

[phadej]

Use ../{foo,bar}/*.cabal

haskell-ci / cabal-install-parsers does cut corners, globs have to match .cabal files. (If I remember right they cannot be local tarballs either, as those aren't supported).

I can confirm that the trailing /*.cabal is needed.
