fmt Strings. (Was: A few comments on porting the Bourne shell) - COFF

Hi Larry,

...
  I hate Python because there is no printf in the base
language.

There's print() with the format-string part being promoted into the
language as the ‘%’ operator when the left operand is a string.
It returns a string.

...
 >> '%10d' % (6*7)
     '        42'
...
 >> '%s %s!\n' % ('hello',
'world')
     'hello world!\n'
...
 >> '%10d' % 6*7
     '         6         6         6         6         6         6        
6'
...
 >> print('foo')
     foo
...
 >> print('%.3s' %
'barxyzzy')
     bar
...
 >> 

So similar to AWK or Perl's sprintf() and Go's fmt.Sprintf() in that it
returns a dynamically-allocated string.
