vi: reinstate timeout of 300 ms

vi: add comments to Rob's algorithm of reading and matching ESC sequences
 (nice work btw!)

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.

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.)
