I screwed this one up.  See #447 for replacement.

The `#!fold-case` and `#!no-fold-case` directives are read as comments, which means that they are treated as whitespace (section 2.2).  Unlike the other kinds of comments, their final delimiter is implicit.  This means that `(1#!no-fold-cases)` reads as `(1 s)`.  This seems unfortunate.

Richard Kelsey proposes terminating them with either `!` or `!#`.  This would break R6RS compatibility.  I propose instead that they must be followed by whitespace.

Per Bothner suggests adding the formal syntax:

{{{
<lexical-directive> -->   #! <identifier>
}}}

and then making the interpretation of `<identifier>` implementation-dependent, except for the standard cases `#!fold-case` and `#!no-fold-case`.
