Tiny glitch in mount script in 2.0.4

[Brent A Nelson <brent@xxxxxxxxxxxx>]

On my hardy system, /bin/sh refers to dash.  The new /sbin/mount.glusterfs 
still uses /bin/sh, but its function definitions have changed from 
"function-name ()" to "function function-name ()", which is bash syntax.

If I change the top line from "#!/bin/sh" to "#!/bin/bash", all is well. 
Otherwise, I get a syntax error at line 21.  For systems where /bin/sh is 
a link to bash, this would not be a problem.

Thanks,

Brent
