A few typos

Hello.

I know that its hard maintain a manual. I was going through the dump command and read_dump command in lammps and I found a few typos.

In the dump command doc pages:

__*custom* of__ *custom/mpiio* args = list of atom attributes

should be custom or custom/mpiio

In the read_dump doc pages:

The *native* format is for native LAMMPS dump files, written with a **"dump atom".html** 

the html should not appear.  

I request the developers to correct this. 

Thanks again for your help.

Arun 

fixed them … thanks
