haddock issue building ghc-7.8 from git

Fri Mar 14 10:08:35 UTC 2014

My goodness am I clumsy sometimes :(

It's actually:

$ git clone -b ghc-7.8 https://git.haskell.org/ghc ghc-7.8
$ cd ghc-7.8
$ ./sync-all get -b ghc-7.8

I messed up the -b argument. Again. :(

As a rule, sync-all for 'get' will take 'git' arguments, so the 'get
-b' translates to 'git clone -b ghc-7.8 ...'

Also, yes, there are already fingerprints. See the source code here:
https://github.com/nomeata/ghc-complete/tree/ghc-7.8 - Note
specifically it is on the 7.8 branch. Also see:

https://ghc.haskell.org/trac/ghc/wiki/Building/GettingTheSources#Trackingthefullrepositorystate

to use the fingerprint utility.

Urgh. Sorry again!
