R devel - Jan 2014 - Format an empty data frame

Hi,

Here seems to be a corner case in which format() fails:
> format(data.frame())
Error in .subset2(x, i, exact = exact) : subscript out of bounds
> sessionInfo()
R version 3.0.2 (2013-09-25)
Platform: x86_64-pc-linux-gnu (64-bit)

locale:
 [1] LC_CTYPE=en_US.UTF-8       LC_NUMERIC=C
LC_TIME=en_US.UTF-8        LC_COLLATE=en_US.UTF-8
 [5] LC_MONETARY=en_US.UTF-8    LC_MESSAGES=en_US.UTF-8
LC_PAPER=en_US.UTF-8       LC_NAME=C
 [9] LC_ADDRESS=C               LC_TELEPHONE=C
LC_MEASUREMENT=en_US.UTF-8 LC_IDENTIFICATION=C

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base


Regards,
Yihui

This behaviour is fixed in R-devel (tested with r64727)
> format( data.frame() )
data frame with 0 columns and 0 rows
