improving commandline documentation/help

[lennart spitzner]

hello cabal devs,

i am willing to put a bit of time into improving the help texts of
cabal-install. some questions:

1) nobody else is working on this, right? is there risk that it
interferes with other's work? (i'd basically touch
Distribution.Simple.Command and the different fooCommand's in both
Setup.hs's)

2) is there a specific reason that the help texts currently are so
short, other than lack of time/focus on functionality? pending large
changes or smth?

3) is there a policy to keep commits touching Cabal and cabal-install
subdirectories separate (for git-subtree purposes, for example)?
