Modify "recommended packages" output to include revision info #3925
Description
Currently, when you run stack build with an impossible build plan, it may give you advice like:
* Recommended action: try adding the following to your extra-deps
in /Users/michael/Documents/markdown/stack.yaml:
- blaze-html-0.9.0.1
- blaze-markup-0.8.2.0
- conduit-extra-1.3.0
- xml-conduit-1.8.0
- xss-sanitize-0.3.5.7
It would be better to include explicit revision information, so that we are recommending people use reproducible build plans.
