1.16.0: Initial cabal update creates invalid config containing unimplemented jobs option

[mietek]

$ cabal update
Config file path source is default config file.
Config file /Users/mietek/.cabal/config not found.
Writing default configuration to /Users/mietek/.cabal/config
Downloading the latest package list from hackage.haskell.org
$ cabal update
cabal: Command.optionToFieldDescr: feature not implemented

It appears the cause of this rather cryptic message is the following line:

$ grep jobs .cabal/config 
jobs: 2

Thanks for the report. This has been fixed in aa7d98f, which will be part of the next bug fix release (due soon).
