Two things are not correct in this command line:

- You need to use back ticks (`) and not single quotes (') aroung the 
v.class command line.
- The example in the description.html was wrong: it should be v.class -g 
so that you do not get the full v.class output, but only the shell style.

This should work:

d.area.thematic map=censusblk_swwake data=total_pop breaks=`v.class -g 
map=censusblk_swwake column=total_pop algo=std nbcla=4` 
colors=0:0:255,0:0:100,100:0:0,255:0:0 layer=1 bwidth=0 bcolor=yellow 
render=l
