my pkg-get wget bug fixed

Found a bug on my pkg-get, detect for wget command, but didn't return the status properly, it was fixed. Seems like I am not familiar with borne shell script. I know borne shell better than korne shell (use by the original pkg-get). The importance of pkg-get is not the script itself, but the packaging and the service which is valuable. I test my pkg-get on Solaris 2.5, seem like working fine.
