emphasize.rownames=FALSE and set.alignment generate error

[alexploner]

Windows 7, R 3.1.1, pander 0.5.2

Trying to show a matrix with named rows and columns with un-emphasized row names after setting the cell alignment produces an error:

require(pander)
jj = matrix(1:4, nrow=2)
rownames(jj) = colnames(jj) = letters[1:2]
jj
##   a b
## a 1 3
## b 2 4
set.alignment("right")
pander(jj, emphasize.rownames=FALSE)
## Error: basic_string::_S_create

FWIW, unsetting either row- or column names of the matrix avoids the error:

colnames(jj) = NULL
set.alignment("right")
pander(jj, emphasize.rownames=FALSE)
## as expected

@RomanTsegelskyi can you please have a look at this? It seems to be rather related to C++, but I'll try to debug it in next few days as well
