Add config("fraction_space") to control spaces around printing fractions

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

Added config("fraction_space", boolean).  The "fraction_space" controls
whether or not a space (' ') is printed before and after fractions.
By default, config("fraction_space") is false.

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

    ; base(1/3),
    ; 1/7
            1/7

With config("fraction_space", 1):

    ; base(1/3),
    ; 1/7
            1 / 7

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

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

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