:browse should browse currently loaded module

[iampure@…]

With module Foo loaded, :browse should be equivalent to :browse Foo.

Good idea. The only slight niggle is that you can have multiple modules loaded (e.g. :m + System.Cmd System.Exit). I don't know if this issue comes up for any other commands, but if not we could just use the first or the last in the list of loaded modules or something.

starting somewhere in 6.7, you can define something like that yourself. the trick is to have a :redir command that allows you to capture ghci command output. then you simply do :show modules, capture the output, and grab one of the modules listed there for :browse.

add the attached cmds.ghci to your .ghci, or source it with :cmd readFile "cmds.ghci". then, :b <mod> will call :browse <mod>, and just :b will call :browse on the first module listed in :show modules. adapt the code to your needs.

there is a patch pending for ghc head that will allow us to avoid having to compress ghci definitions into single lines, which will make things like this a lot more readable and maintainable..

First merged; second is in the shared testsuite, so no merge needed.
