John responded in email:

As I recall, it was necessary to ensure that any syntax from, say, /etc/pspp/rc
got executed.   Maybe it is no longer required.  If all the startup options
continue to work properly, please feel free to remove it.

[John, question for you below]

The reason that PSPPIRE opens an empty output window on startup is that psppire.c's "initialize" function does, as its last step, the following:

execute_const_syntax_string (data_window, "");

and running any syntax (even empty syntax) causes that syntax to be written to the output window as a side effect.

John, you introduced that call (in slightly different form) without further explanation  in commit fe76b9c2c "Rewrote the command line parser using argp."  Removing it seems to have no ill effects.  Do you know of a reason to keep it?

When PSPPIRE starts it opens an empty output screen. This looks odd.
