Tom Tromey 984ee559a2 Fix "set" handling of Python parameters ...

It's long bothered me that setting a Python parameter from the CLI
will print the "set" help text by default.  I think usually "set"
commands should be silent.  And, while you can modify this behavior a
bit by providing a "get_set_string" method, if this method returns an
empty string, a blank line will be printed.

This patch removes the "help" behavior and changes the get_set_string
behavior to avoid printing a blank line.  The code has a comment about
preserving API behavior, but I don't think this is truly important;
and in any case the workaround -- implementing get_set_string -- is
trivial.

Regression tested on x86-64 Fedora 26.
