Incorporate vim-argumentative text objects and motions for function arguments

[bruce-hill]

The Argumentative plugin for vim is a super useful plugin that adds motions and text objects for manipulating function call arguments. For example, you can da, to delete around a function argument, which deletes the argument and any comma delimiter as needed. You can also use >, or <, to shift the argument left or right among the argument list. It would be really nice to have this feature, since I use it all the time in vim.

Examples

Before pressing da, (delete around argument) (cursor is ▒)

foo(1 + ▒some_func(), 2, 3)

After pressing da,:

foo(▒2, 3)

Before pressing >, (shift argument right):

foo(1 + ▒some_func(), 2, 3)

After pressing >,:

foo(2, 1 + some_func()▒, 3)

Note: this also works on lists/arrays/etc.
