At present, Lua-5.1.4 manual does *NOT* link %d to 32-bit integers but
think that it should.

Here is relevant paragraph:

string.format (formatstring, ···)
Returns a formatted version of its variable number of arguments
following the description given in its first argument (which must be a
string). The format string follows the same rules as the printf family
of standard C functions. The only differences are that the
options/modifiers *, l, L, n, p, and h are not supported and that
there is an extra option, q. The q option formats a string in a form
suitable to be safely read back by the Lua interpreter: the string is
written between double quotes, and all double quotes, newlines,
embedded zeros, and backslashes in the string are correctly escaped
when written. For instance, the call

     string.format('%q', 'a string with "quotes" and \n new line')

will produce the string:

     "a string with \"quotes\" and \
      new line"

The options c, d, E, e, f, g, G, i, o, u, X, and x all expect a number
as argument, whereas q and s expect a string.

This function does not accept string values containing embedded zeros,
except as arguments to the q option.
