Add WISH_PATH_POWERLINE_MAX_PERC to limit path length. 

WISH_PATH_POWERLINE_MAX_PERC tries to ensure that the path stays below
the specified percentage of the remaining characters. The path is
shortened by replacing each dir with its initial until it becomes short
enough. The last part is never shortened.
