DEC ANSI command sequence questions; cursor movement

I got in touch with Thomas Dickey (invisible-island.net) who maintains xterm and vttest - he explained that CSI 0 C is the same as CSI 1 C or CSI C in xterm.

For anyone looking for more information on terminal programming I highly recommend checking out the xterm source he hosts - specifically the ctlseqs.txt inside xterm, which looks very much like the one true terminal control sequences reference I've been searching for.
