- In 19f through 20b, READ-SEQUENCE could read mostly arbitrary
data from a stream in to the given sequence. In this release,
READ-SEQUENCE cannot do that unless the stream is a
binary-text-stream. This is an incompatible change from
previous releases.

- Fixes for signaling errors with READ-CHAR and READ-BYTE
o READ-CHAR signals errors if the stream is not a character
stream. This is a change from 20a and 20b, but matches
releases before 19f. (Almost. 19f allowed reading characters
from (unsigned-byte 8) streams. 19e did not.)
o READ-BYTE signals errors if the stream is not a binary
stream. This is also a change from 20a and 20b, but matches
releases before 19f. (Almost. 19f allowed reading bytes from
character streams. 19e did not.)
o But READ-CHAR and READ-BYTE will work if the stream class is
'binary-text-stream, an extension for bivalent streams in
CMUCL. READ-CHAR will use the specified external format for
such streams. READ-BYTE reads (unsigned-byte 8) elements from
such streams.
