STEVIE bug fix

[Jose Vasconcellos]

Under OS/2 STEVIE core dumps when attempting to search for an empty
string. Also, pressing ':' and <ret> causes and invalid command message.
The following change fixes both.

Insert the two lines marked with '+' at the end of routine getcmdln
in module cmdline:

        }
+       if (buff[0] == '\0')
+               return NULL;
        return buff;
}
