412,build-reports: option is invalid in a config file,guest,,"With darcs (tonight) cabal and cabal-install, I see the generated .cabal/config includes the line '-- build-reports:', suggesting that this is a valid configuration option.

However, it is not. If one uncomments it to 'build-reports: True', then Cabal warns and apparently ignores one's configuration as corrupt:

gwern@craft:29302~>cabal update
Warning: Error parsing config file /home/gwern/.cabal/config:9: ""True""
Warning: Using default configuration.

The syntax is valid, the True is correct, it's not listed as being part of a section. further, --build-reports is a valid CLI option:

gwern@craft:29304~>rm .cabal/config && mv config .cabal && cabal install --build-reports ztail                       [ 9:21PM]
