Changed the XMonad.Action.Search to use a function instead of String to prepare the search URL.Added a few useful functions used to connect many search engines together and do intelligent prefixed searches (more doc in haddock)The API has not changed with the only exception of search function, which now accepts a function instead of String.
It's inappropriate because if I am searching Wikipedia, say, why on earth do I want completion of files and executables on my PC? A previous search query is much more likely to be what I want.
The new getBrowser function allows us to mv the old selectSearch and promptSearch aside as too-general functions, and replace them with new versions, which employ getBrowser to supply one more argument. This allows us to replace the tedious 'selectSearch google "firefox"; selectSearch yahoo "firefox"...' with shorter 'selectSearch google' and so on. One less argument.
Also, update the docs.
This removes whitespace in source code snippets. Because Haddock renders quoted source code as monospaced unwrappable text, the excess whitespace meant you would have to scroll horizontally, unpleasantly.
