R help - Nov 2009 - Suppressing final spaces in data.frame printouts

When printing data.frames, R aligns columns by padding with spaces.
For example,

print(data.frame(x=c('a','bb','ccc')),right=FALSE)
? x
1 a? |------------------ vertical bar shows end of line
2 bb |------------------ vertical bar shows end of line
3 ccc|------------------ vertical bar shows end of line

Is there some way to suppress the padding for the final column? I
often have data frames which contain a handful of long strings in the
final column which, when printed out, cause wraparound on all the
rows, even those not containing long strings, something like this:

print(data.frame(q=1:3,x=c('a','bb','this is a very long
string')),right=FALSE)
? q x?????????????? |
????????? |
1 1 a?????????????? |
????????? |
2 2 bb????????????? |
????????? |
3 3 this is a very l|
ong string|

where I'd rather have

print(data.frame(q=1:3,x=c('a','bb','this is a very long
string')),right=FALSE)
  q x|
1 1 a|
2 2 bb|
3 3 this is a very l|
ong string|

I could of course write my own print function for this, but was
wondering if there was a standard way of doing it.  If not in R,
perhaps there is some way to have ESS delete the final spaces?

Thanks,

ESS, or more precisely emacs, can handle that.  Use the M-x 
toggle-truncate-lines command:
     Toggle whether to fold or truncate long lines for the current buffer.
