+ * ESC-Z processing:
+ *
+ * By stealing a sequence to which other xterms respond, and sending the
+ * same number of characters, but having a distinguishable sequence,
+ * we can avoid having a timeout (when not under an rxvt) for every login
+ * shell to auto-set its DISPLAY.
+ *
+ * This particular sequence is even explicitly stated as obsolete since
+ * about 1985, so only very old software is likely to be confused, a
+ * confusion which can likely be remedied through termcap or TERM. Frankly,
+ * I doubt anyone will even notice. We provide a #ifdef just in case they
+ * don't care about auto-display setting. Just in case the ancient
+ * software in question is broken enough to be case insensitive to the 'c'
+ * character in the answerback string, we make the distinguishing
+ * characteristic be capitalization of that character. The length of the
+ * two strings should be the same so that identical read (2) calls may be
+ * used.
