[R] weird behavior of nsmall in format

It adds zeros fine but for format(0.123456789, nsmall = 1) I want the
result to be 0.1.

I want to format numbers with a fixed number of digits.  A combination of
round and format + nsmall does the job.  sprintf will do it too, but I
wondered if the current implementation of nsmall in format is correct.

Thanks,
