Provide one text object instead of of two

[szw]

Provide only one text object behaving differently depending on the
current filetype. It doesn't include the line below the indent text for
file types where indentantion is a part of the syntax. Currently it
means Python, CoffeeScript, and Haml buffers. This can be extended as
necessary.

If accepted the doc/indent-object.txt should be changed accordingly.

Thank you for your commit.

I'm not sure what the best way to go about this is. At the moment it's quite easy to make a mapping for the preferred mode for the current file. I'm not necessarily sure that hard-coding a list of file types is the best approach here?

If we wanted to go down this route, I think it would make sense to implement the switching as file-type-specific plugins, maybe?

I like the way they did it in vim-pasta plugin: https://github.com/sickill/vim-pasta/blob/master/plugin/pasta.vim#L60
