Fix warnings: Early returns in non-void functions.

[XtraIce]

Instead of returning early in the for-loops, insert a break line and then return at the end of the function instead.
This gets rid of the bunch of warnings this library causes.

I have the code to fix, if want me to branch and do PR.

@XtraIce Can you open a pull request so others than see the changes. Better yet, fork this project as the owner seems absent. For me, the warnings are now errors so I've got to address them.

Thanks
