This is a hugely incompatible change.  It would break every (for-each
display ...) out there.  My employer has a lot of exports to delimited
files, and this would insert spurious white space around numbers.
 
For display, I'd strongly suggest not incompatibly changing the
behavior.  Rather create a new function name for the space-inserting
functionality.  That might make xquery harder to implement, but it's
important for Scheme.

For write, I don't directly know of code that would break, but I'd
hesitate about putting that change in too.  Stay compatible with other
implementations as far as practical.
