1793/* Unhandled complications -
1794Less and more have the "ZZ" command, but nothing else seems to have multi ordinary character commands.
1795
1796Some editors have a shortcut command concept. The smallest unique first part of each command will match, as well as anything longer.
1797 A further complication is if we are not implementing some commands that might change what is "shortest unique prefix".
1798
1799The response from a terminal size check command includes a prefix, a suffix, with the data in the middle.
1800 send "\x1B[s\x1B[999C\x1B[999B\x1B[6n\x1B[u"
1801 Which breaks down to - save cursor position, down 999, right 999, request cursor position (DSR), restore cursor position.
1802 response is "\x1B[ ; R", where the spaces are replaced by digits LINES and COLUMNS respectively.
1803 And just to screw things up - {"\x1B[1;2R", "Shift F3"}, though no one's going to have a 1 x 2 terminal.
