interrupt, so we don't need to worry about scheduler delays. This means the

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

fixed the "dot" (i.e. '.') command, to properly re-init its

buffer between commands, not recalculate its length all the time,
and to not reallocate its fixed-length buffer frequently.
fixed the 'c', 'd', and 'y' commands to properly handle both motions
that are just part of a line, and those that are multiline. for
instance, now "c%" and "2cw" work correctly, whether the motions span
lines or not.
added some permissble motions for 'c', 'd', and 'y': namely 'h',
'l', SPACE, BS, and DEL
