  If that last one is changed to %-20 (sh doesn't like "var= val"),
and people don't mind 0-padded numbers, then yes this is
source-able by sh.  Oops -- one can specify %-7d for 32-bit
numbers, and get blank-padded on the right.  So sprintf can do it
all, after all.

  If I end up going this way (versus Jukka's ideas), though,
I'd probably write up several mini-routines for printing, for
efficiency reasons (if benchmarking shows that they are
sufficiently faster than the general-case-handling sprintf), in
which case it would be trivial to add right-padding of numbers
and strings.
