that it is output to the terminal if the new rebar.conf option
'cover_print_enabled' is set to true.

The previous fix to relax the regex was insufficient.
This is basically the diff proposed by Bryan Fink with
the difference of using 'C' instead of 'en_US'.

rebar_utils:sh/2 terminates on error and does not return an error code
as expected.

Based on http://gist.github.com/539516.

Rebar currently doesn't give any feedback on an invalid command. This change
makes rebar keep track of how many operations each command triggers, if a
particular command doesn't change the count, there were no modules implementing
it. If at the end of handling all commands, tje count is 0, none of the supplied
commands were valid and ?FAIL is called to trigger a non zero exit status.

Erroneously put rebar_pre_script at the end of the app_dir modules
list in the previous commit.
