PSPPIRE doesn't run an rc file or other syntax at startup.  The
code to do that is in src/ui/terminal.  So I've removed the
execute_const_syntax_string() call now.

Did some earlier version of PSPPIRE run an rc syntax file at
startup time?  Do you think that it should?  If so, we can add
code to do that.
