#rm(modify_vimrc = true) ⇒ Object

1) Remove the line ‘Bundle plugin_name` or `Plugin plugin_name` from .vimrc. 2) Look for a file in the settings directory (provided by option –settings)

with name that includes the plugin name. Then ask if the user wants to remove it.

3) Remove the plugin directory.
