stack.yaml package field pointing to *.*.cabal not found

[haroldcarr]

I added:

packages:
- '.'
- /Users/carr/openhc/test-hunit-util

but got:

> stack build
No .cabal file found in directory /Users/carr/openhc/test-hunit-util/

The cabal file in that location is named Test.HUnit.Util.cabal. If I rename the file to Test-HUnit-Util.cabal then it is found

(although, it then has other unrelated problems:

cabal file /Users/carr/openhc/test-hunit-util/Test-HUnit-Util.cabal has a mismatched package name: Test-HUnit-Util

)

(although, it then has other unrelated problems:

This is intended behavior: Hackage and cabal have inconsistent behavior around mismatching package/file names, and in stack we've decided to be consistent and enforce matching names. For details, see: #317

We can improve the first part about finding .cabal files with periods in them.

I've updated master with better code for displaying accurate error messages. Now, it says things like:

cabal file path /home/vagrant/Desktop/periods/foo.bar.cabal does not match the package name it defines.
Please rename the file to: periods.cabal
