[Michael Larson]

Here's a small fix for the xorpsh when the TERM environmental variable is not set:

        ; // do nothing
 #else
-       term_name = getenv("TERM");
-       if (term_name.empty())
+       char *term = getenv("TERM");
+       if (term == NULL || string(term).empty() == true)
            term_name = DEFAULT_TERM_TYPE;      // Set to default
 #endif
     }

The getenv is returning a NULL ptr which causes a crash when the assignment is applied to the string term_name. The fix is to check for NULL prior to testing for an empty string.
