the mode, not the timeout. Here, "100" happens to be 0x64 which includes
K_SPIN which indicates it was called from getkey(K_SPIN) and since it wasn't,
it was removing the last character of the save-line buffer since this code also
does gratuitous save/restoreline() calls, resulting in partial ANSI escape
sequences being displayed at the command-line. This one too far too long to
find. :-(
