	output "???"  if the string cannot be parsed as an inexact number.

1999-06-06  Aubrey Jaffer  <jaffer@ai.mit.edu>

	string, stick a #f on the front of it, so it is now a valid CL
	format argument list.  This is easier than changing everyplace
	else (like the error formatter) that expects it to be in CL form.
	The other clause which explicitly tests for this case is now dead
	code; remove it.

	which format like %g, except that an SI prefix is output after the
	number, which is scaled accordingly.  %K outputs a space between
	number and prefix, %k does not.  It would be good to allow %f and
	%e like formatting, but it's not clear how to fit this into the
	format string syntax.

	(chez:merge!): had a typo.
	(defmacro:load): (require 'struct) didn't work, because defmacro:load

	of a <variable> did not include the <step> expression and the
	<test> expression, instead it incorrectly included the <init>
	expression. (rf. R4RS, 4.2.4)
	(hyg:tag-lambda): the body of a lambda expression should be
	generated using hyg:tag-generic instead of hyg:tag-vanilla. This
	allows expressions within lambda to behave hygienically.

Thu Mar  3 23:06:41 1994  Aubrey Jaffer  (jaffer@jacal)

	From: lutzeb@cs.tu-berlin.de (Dirk Lutzebaeck)
	* format.scm slib.texi: Format 3.0.
  * format's configuration is rearranged to fit only into SLIB. All
    implementation dependent configurations are done in the SLIB init files
  * format's output routines rely on call-with-output-string now if
    output to a string is desired
  * The floating point formatting code (formatfl.scm) moved into
    format.scm so that there is only one source code file; this
    eliminates the configuration of the load path for the former
    formatfl.scm and the unspecified scope of the load primitive
  * floating point formatting doesn't use any floating point operation or
    procedure except number->string now; all formatting is now based
    solely on string, character and integer manipulations
  * major rewrite of the floating point formatting code; use global
    buffers now
  * ~f,~e,~g, ~$ may use also number strings as an argument
  * ~r, ~:r, ~@r, ~:@r roman numeral, and ordinal and cardinal
    English number printing added (from dorai@cs.rice.edu)
  * ~a has now a working `colinc' parameter
  * ~t tabulate directive implemented
  * ~/ gives a tabulator character now (was ~T in version < 2.4)
  * ~& fresh line directive implemented
  * ~@d, ~@b, ~@o and ~@x now has the CL meaning (plus sign printed)
    automatic prefixing of radix representation is removed
  * ~i prints complex numbers as ~f~@fi with passed parameters
  * ~:c prints control characters like emacs (eg. ^C) and 8bit characters
    as an octal number
  * ~q gives information and copyright notice on this format implementation
    ~:q gives format:version
  * case type of symbol conversion can now be forced (see
    format:symbol-case-conv in format.scm)
  * case type of the representation of internal objects can now be
    forced (see format:iobj-case-conv format.scm)
  * format error messages are now printed on the current error port
    if available by the implementation
  * format now accepts a number as a destination port; the output
    is then always directed to the current error port if available by
    the implementation
  * if format's destination is a string it is regarded as a format string now
    and output is the current output port; this is a contribution to
    Scheme->C to use format with the runtime system; the former semantics
    to append tothe destination string is given up
  * obj->string syntax change and speedup
  * tested with scm4d, Elk 2.2, MIT Scheme 7.1, Scheme->C 01Nov91
