020f40693a line editing: add an option to emit ESC [ 6 n and use results 
This makes line editing able to recognize case when
cursor was not at the beginning of the line. It may also
be adapted later to find out display size (serial line users
would love it).

7960ea8918 Confirmed that on Linux the serial interrupt takes precedence over the timer 
interrupt, so we don't need to worry about scheduler delays.  This means the
delay can be trimmed down to 25 miliseconds.  Add comment while at it.

988dd5549b Clean up editors/vi.c:readit() so it only does readahead when actually 
parsing an escape sequence.  (This mitigates but doesn't fully fix the
the "cursoring around the file deletes data under qemu" bug, presumably due
to "\033[D" being treated as three separate characters.)

2724fa9d8a remove alarm() calls which were functioning as a primitive 
watchdog function, presumably to catch infinite loop bugs. 
(control-C can do the same thing, and the alarms were too short in
any case.)  also, switch to sigsetjmp/siglongjmp in order to allow
repeated use of control-C -- otherwise it works once, then not again.
