*g:ag_working_path_mode*
A mapping that describes where ag will be run. Default is the current working
directory. Specifying 'r' as the argument will tell it to run from the project
rootdirectory. For now any other mapping will result to the default.
Example:
rootdirectory. For now any other mapping will result to the default. The
function that locates the root directory can be customized with
|g:Ag_get_project_root|. Example: >
let g:ag_working_path_mode='r'
