+blinking cursor
+===============
+
+Description
+-----------
+This patch allows the use of a blinking cursor.
+
+To demonstrate the available cursor styles, try these commands:
+ echo -e -n "\x1b[\x30 q" # blinking block
+ echo -e -n "\x1b[\x31 q" # blinking block (default)
+ echo -e -n "\x1b[\x32 q" # steady block
+ echo -e -n "\x1b[\x33 q" # blinking underline
+ echo -e -n "\x1b[\x34 q" # steady underline
+ echo -e -n "\x1b[\x35 q" # blinking bar
+ echo -e -n "\x1b[\x36 q" # steady bar
+
+Notes
+-----
+* Only cursor styles 0, 1, 3, and 5 blink. Set `cursorstyle` accordingly.
+* Cursor styles are defined [here](https://invisible-island.net/xterm/ctlseqs/ctlseqs.html#h4-Functions-using-CSI-_-ordered-by-the-final-character-lparen-s-rparen:CSI-Ps-SP-q.1D81).
