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).

582dff0514 volume identification: abolish /proc/partitions and /proc/cdroms

Adding even more cruft is bad, so I decided to simply

it finds devices now:

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.

5e38cd910a Escape sequences sent over serial links don't come in as a block, so poll
needs to pause a bit to make sure the next character has time to come in.

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.)
