pssh - allow command to come in from stdin

[GoogleCodeExporter]

Currently it's possible to pass ssh a script via stdin to run on the remote
machine like:

ssh user@host < script.sh

but when I try the equivalent with pssh:

pssh -h hosts.txt < script.sh

I get an error "pssh: error: Command not specified".

Would it be possible for pssh to allow the command to be run on the remote
machines come in via stdin like ssh does?

Interesting.  I've never even realized that ssh lets you do that.  I think this 
might 
need a little more thought before plunging ahead.  For example, what should 
happen if 
someone doesn't specify a command but doesn't give any input on stdin either?  
Should 
pssh throw an error in this case?

I've made and commited a -I option as a fix for issue #12.  I've also commited 
a 
change that allows the script to be passed on standard input (when -I is 
given), but 
if I get negative feedback about the -I option, this might need to be revisited.

Please try out the latest changes (in the Git repository), and let me know what 
you 
think.  Be sure to chime in on issue #12 if you have an opinion about that.

Thanks for your help with pssh.

I haven't heard back since I made the fix, so for now I'll assume that this 
works.  
I'll close the bug, but please reopen it if you have any problems.  Thanks for 
your 
contribution.
