[PATCH] Minor portability patch to git-submodule

[Andy Dougherty <doughera@lafayette.edu>]

While trying git out on Solaris 8, I needed the following patch.  
The 'grep' command on Solaris doesn't understand the -e option, though 
egrep does. 

More mysterious is the printf patch.  Without it, the sed command didn't 
match anything.
