220.127.116.11: Optimize READ-SEQUENCE into strings and READ-LINE
* Have READ-LINE and READ-SEQUENCE directly use the cin buffer whenever
one exists, instead of going through FAST-READ-CHAR. READ-LINE already
did this in some circumstances, but often .
* READ-LINE on normal data with short lines is around 50% faster, with
abnormally long lines about 75% faster. (On my laptop -- IIRC the
difference was smaller on a workstation).
* READ-SEQUENCE into a simple string is up to 80% faster.
* Modify FAST-READ-CHAR-REFILL a bit to make it nicer to use in the
* Fix a utf-8 resyncing bug in READ-LINE (masked by the test case
in external-format.impure not having a newline at the end, which
caused READ-LINE to always take the slow path).
