Add config("complex_space") to control spaces around + or - in complex values

Browse Source 
Added config("fraction_space", boolean) to help/config, along with
a few few minor text improvements.  Updated cal/regress to test
config("tilde_space").

Added config("complex_space", boolean).  The "complex_space" controls
whether or not a space (' ') is printed before and after the + or -
in complex values.

By default, config("complex_space") is false.

For example, with the default, config("complex_space", 0):

    ; asin(2)
	    1.57079632679489661923-1.31695789692481670863i

With config("complex_space", 1):

    ; asin(2)
	    1.57079632679489661923 - 1.31695789692481670863i

NOTE: Use of config("complex_space", 1) can break printing and scanning
      of fractional values via "%r".

NOTE: Use of config("complex_space", 1) can break printing and scanning
      of complex values via "%c".

Added config("complex_space", boolean) to help/config, along with
a few few minor text improvements.  Updated cal/regress to test
config("complex_space").
