/**
+ * BUGS
+ * ----
+ * Known bugs and problems:
+ *
+ * Redrawing of the main view while loading::
+ * If only part of a commit has been parsed not all fields will be visible
+ * or even redrawn when the whole commit have loaded. This can be
+ * triggered when continuously moving to the last line. Use 'r' to redraw
+ * the whole screen.
+ *
+ * TODO
+ * ----
+ * Features that should be explored.
+ *
+ * - Proper command line handling; ability to take the command that should be
+ * shown. Example:
+ *
+ * $ tig log -p
+ *
+ * - Internal command line (exmode-inspired) which allows to specify what git
+ * log or git diff command to run. Example:
+ *
+ * :log -p
+ *
+ * - Proper resizing support. I am yet to figure out whether catching SIGWINCH
+ * is preferred over using ncurses' built-in support for resizing.
+ *
+ * - Locale support.
