Filter filename when executing Haskell-based config
We are now—in case the user specified a Haskell file as their xmobar configuration—threading the command line arguments that xmobar receives to the relevant execv() call. However, we simply shove in all arguments originally given to xmobar, including the path to the configuration file. As main is now defined within that very file, this seems unneccessary. By filtering out that part of the arguments, the pattern that a lot of users seem to follow for easy setting of certain options becomes a little bit nicer. For example: main :: IO () main = getArgs >>= \case ["-x", n, _] -> xmobar . config $ read n _ -> xmobar $ config 0 becomes main :: IO () main = getArgs >>= \case ["-x", n] -> xmobar . config $ read n _ -> xmobar $ config 0 Related: https://github.com/jaor/xmobar/pull/553
