[R6RS] a typo and some lexical issues

[William D Clinger]

During proofreading, I ran across a few things that look
wrong but I didn't know how to fix:

In the formal syntax of add-prefix, what is the prefix?

Lexical issues
==============

#x1A and #X1a are alleged to be the same, but the formal
lexical syntax doesn't generate #X1a.

#x1AB and #X1ab are alleged to be the same, but the formal
lexical syntax doesn't generate #X1ab.  This second
allegation comes only four paragraphs after the previous.

Are #T and #F legal?

Is 3+4i the same as 3+4I?

Are 1E3, 1S3, 1F3, 1D3, 1L3 legal?

Are #E3 and #I3 legal?

Are #B1001, #O1001, and #D1001 legal?

Presumably "\X97;" is illegal?
