keywords have no read/write invariance

[sjamaan]

$ csi
#;1> (string->keyword "foo bar") ; Should be escaped
foo bar:
#;2> |foo bar|:                  ; Handled correctly by the reader
foo bar:
#;3> #:|foo bar|                 ; I don't know *what* is going on here!
|foo:

And

$ csi -K prefix
#;1> (string->keyword "foo bar")  ; should be escaped
:foo bar
#;2> :|foo bar|                   ; Handled correctly by the reader
:foo bar

I expect a keyword with a space in it to be serialised like the symbol and followed by a colon (or preceded, depending on the keyword style). The reader should handle the {{#:}}} prefix no different from the mode-specific syntax.

It turns out that #:|foo bar| is read by the simple tokenizer, instead of the extended symbol tokenizer that deals with pipe escapes.
