1306 * Features that should be explored.
1308 * - Dynamic scaling of line number indentation.
1310 * - Proper command line handling; ability to take the command that should be
1315 * - Internal command line (exmode-inspired) which allows to specify what git
1316 * log or git diff command to run. Example:
1320 * - Proper resizing support. I am yet to figure out whether catching SIGWINCH
1321 * is preferred over using ncurses' built-in support for resizing.
