typo in bash manual

[Dave Yost]

In http://www.gnu.org/software/bash/manual/bashref.html#GNU-Parallel

Where you say
ls *.gz | parallel -j+0 "zcat {} | bzip2 >{.}.bz2 && rm {}"
This will recompress all files in the current directory with names ending in 
.gz using bzip2, running one job per CPU (-j+0) in parallel.

it should be
ls *.gz | parallel -j+0 "zcat {} | bzip2 >{.}.bz2 && rm {}"
This will recompress all files in the current directory with names ending in 
.bz2 using bzip2, running one job per CPU (-j+0) in parallel.


Also, you should mention what the +0 does.
