`yi-core` fails to build with GHC 7.10

[andreasabel]

$ cabal install yi-core -w ghc-7.10.3
Building library for yi-core-0.19.2..

src/Yi/Buffer/HighLevel.hs:130:18-35:
    Could not find module ‘Data.List.NonEmpty’
    It is a member of the hidden package ‘semigroups-0.19.1@IfBn1hkRmOv6mXQ39hiLLF
    Perhaps you need to add ‘semigroups’ to the build-depends in your .cabal file.

I made a revision on hackage to require base >= 4.9: https://hackage.haskell.org/package/yi-core-0.19.2/revisions/

Please bump to base >= 4.9 if you do not intend to support GHC 7.10.

Same problem for:

• yi-keymap-emacs
• yi-keymap-vim
• yi-mode-javascript
